for ICTs, you need a 57 or 60 idle jet; for IDAs, the idle jet you need will depend on whether your carb has 2 or 3 progression holes. Main jet plug seal (15)
People often will shell out the bucks for a new carburetor, bolt it on right out of the box, and seem "pleased" with the results. Any auto supply store can sell you a little T-shaped adaptor that will fit on the terminal, with three "wings" (if you will) to which the three black wires can be attached. The effect is clearly noticeable from 3000 RPM upwards (just under 60 mph), and probably a little lower than that. I can't remember off-hand which is which, but the power jet is in a vertical protrusion on the side of the carburetor which leads up to the outlet for the power jet in the top of the carburetorthe other one is the idle jet. The stock carb has a 26mm venturi. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. Use stock vacuum line from air-intake #4 for CDI control unit. We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. $7.99. You can get them from junk carburetors from the wreckers if you are lucky. Carburetor Disassembly
Most carburetors come out of the box with a 55-60 idle jet. Accelerator pump diaphragm (24)
So, I let it warm up, and set the timing to 32 degrees full advance. Do you know what size high speed jet you have? So a 34PICT/3 carburetor with an 009 distributor should be jetted with an X130 or X132.5 main jet, and an 80-100Z air correction. Choke vacuum diaphragm (38)
Which one is which one? It's important that you get it right. Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. SUPER-STOCK-34-3. The auxiliary (power) fuel jet is a small brass jet screwed into the right side of the carburettor, sittin in a protrusion running up to the top. With the idle cut-off valve working correctly, hot spots in the cylinders don't occur as readily, since there is no fuel available to keep the engine running once you turn off the ignition. The venturi sizes listed below are the sizes supplied by Weber in new carburetors. . I would stick with the 34 pict 3 carb with the dual port. I played with the timing, the volume screw, almost everything, I even found a X120 main jet and tried that as well, but she's still failing. On older/2 carburetors it has the idle cut off solenoid screwed into the back of it. Using a new gasket, install the carburetor on the intake manifold flange. Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex . On some models (the H30/31 for example) it is angled slightly towards the back of the car. Except for the fact that it won't idle! We are now only fulfilling order requests only for items that we have in stock OR that we know can be acquired within a defined timeframe. I have EMPI 34 pict 3 on GL1100 55 jet 130 jet idles 1000-1100. ). Rebuild. You also set the accelerator pump for maximum stroke when using the 009. If the valve sticks in the open position, the idle fuel circuit will remain open, so if the engine is still turning it will still draw fuel through the idle jet, resulting in running on if there is a hot spot in one or more cylinders. The air correction jet has to be the right size for the same reason. Make sure this fits by entering your model number. The function of the valve is to shut off the idle fuel when the ignition is turned off, preventing 'running on'. That's fine for modern cars with engine computers which can adjust the mixture on-the-run, but what about our old fixed-jet carburettors? Note: Regarding "drilling out" the main jet, please see our article on Tuning the 009 Distributor/
We are a "lean-staffed" small business and email care is how we are able to best take care of your aircooled parts needs! PRODUCT IMAGES are representative only. Lightly lubricate the choke valve shaft and throttle valve shaft with engine oil and the external linkage with molybdenum grease. None of these tests are definitive - just indicative. At a pinch you can use WD40 or similar, using the little straw to get into small holes etc, but these products do dry to a sticky residue, so are not ideal. When used with the heavy bodied Type 2 vehicle and a vacuum distributor, it should work well with a 60 or 65 idle jet, 125 (or just maybe 127.5) main jet and a 125 air correction jet. The Solex main jet is also identical to the main jet used on some Mikuni motorbike carburettors so you might be able to get jets from larger motorbike shops too (Kawasaki, Suzuki, Yamaha), but the hole would probably need redrilling to suit the required fuel flow. (The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. With lean jetting you are likely to need more throttle and have slightly worse fuel economy - using the slightly richer settings I'd suggested above will give you a little more power and a cooler running engine, so hopefully fuel economy will improve a little, but don't expect too much - fuel economy with the heavy Type 2 body is never very good. The H30/31 is the largest carburetor you can use with the normal single-port manifold. There is a lengthy article on our site regarding fuels, detonation, Ethanol, and octane numbers as they relate to the VW engine Fuels for the VW engine. Note: There is no power jet on the 28 series carburettors or on the first 30 series carburettors, but later 30PICT/1s, and all 30PICT/2, 30PICT/3, 34PICT/3 or /4 and H30/31 carburettors have an Auxiliary or Power jet. We have had great results with these factory bench tested carburetors. The exhaust system peashooters started turning black inside as soon as I put the larger jet in. Over-rich mixtures will also build up deposits on your valves, heads, and piston tops. Remove the main jet (as above) and blow through it (check for crud in the float bowl at the same time). Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. All three of these jets can be changed. = Uses .0 Bypass: WEBER 34 ICT: Factory Sizes: Single Carb: Dual Carbs: AIR CORRECTION 1.60 N/A 1.60 EMULSION TUBE F-78 N/A MAIN . The Pilot Jet Valve (idle jet) would be the g55. Note: The air correction jet size is very important when using a smaller carburetor on a larger engine (e.g., a 30PICT on a 1600cc DP engine). Another well respected and active VW carburettor rebuilder is TIM. Checking and adjusting cold idle speed =>page 22-53 Throttle valve positioner Soot will indicate the main jet is a little too large. Some tests to help you determine proper jetting. The 1200cc engines usually used a X120 or X122.5 in the 28PICT carburetors, the 1300cc engines used either X122.5 or X125 in the 30PICT carburetors, the 1500cc engines usually used a X125, and the 1600cc engines usually need a X127.5 in either 30PICT, H30/31, or 34PICT, but MIGHT get away with an X125 in the smaller 30PICT and the H30/31. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. So with a vacuum distributor, using a 55 idle, X130 or X132.5 main and about a 100 - 120Z air correction jet should provide good mixture for a 1776, without affecting fuel economy to badly (fuel consumption WILL be a little higher with the larger capacity though). The proprietor of Aircooled.Net thinks the main jet is a size X130, and the idle jet is size 50.) The following topics are discussed in this article -. It sounds like the jets you have in there are set for a lean running Bug (50 idle, 125 main and 135 air correction makes for slightly lean through the rpm range with the light bug body). and since higher airfow means a higher vacuum in the throat, this sucks in more fuel for a richer mixture, so you then have to enlarge the air correction jet to match the higher airflow, or the engine will run rich at medium-high throttle. The air correction jet must be SMALLER to enrichen the mixture. Made-to-order, Special-Order, and Direct-shipped items with longer advertised manufacture and/or fulfillment lead times will NOT be auto-canceled, and will be fulfilled in the longer, as-advertised timeframe. Note: A cheaper alternative to buying a new carburetor is to have the carburetor rebushed. I haven't run enough through the tank to get a real idea about consumption yet, but since I don't notice any huge difference in performance I'll probably be going back to the X125 soon. Dave jetted his new carburetor as follows: main jet - X130; idle jet - 55; air correction jet - 80Z. But optimum performance and MPG will be achieved when you use a wide band and tune the carb for 16:1 A/F on cruise, and 13:1 over 1/2 throttle. You should see some air come out of the progression holes in the carburetor throat just near the throttle butterfly when it's in the closed position. The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application. (See our Automatic Choke Discussion and Adjustment Procedure.). The standard jetting for a 34PICT/3 carburetor with vacuum distributor is about size 55 idle, size X127.5 main, and size 100Z-120Z air correction jets. 2-F7 emulsion tubes for the IDF. On the twin port engines, it has to be used with a 30/34 adaptor, since the twin port manifold has a larger mounting flange than the single port manifold. . 60 day return. They are cheap enough. Once all together, retune the carbs (mixture and idle speeds) as per standard VW tuning methods. Useful experiment anyway. Look down into the top of the carburetor to make sure that the screwdriver is squarely in the slot in the jet and that the threads line up squarely, then just screw it in (the small screw driver sits deep in the slot in the jet and helps line it up). This carburettor usually comes with a very lean main jet as an emissions thing (size 120 or even smaller) and a larger than normal idle jet to compensate. To compensate for this, an air correction jet is inserted in the fuel delivery circuit after the main jet, which starts to add air to the fuel emulsion as the airflow increases. Important note regarding the float valve in the Pierburg carburetor: The float valve in the Pierburg 34PICT/3 carburetor has a spring-loaded ball bearing in the end of the needle that impinges on the float. Regarding the 1776cc engine: the stock 34PICT/3 carburetor with a fractionally larger main jet and a fractionally smaller air correction jet to suit the higher air flow being asked of the carburetor should suit nicely. At the beginning I started to use a Solex 30 PICT-2. Most 34PICT/3 carburetors don't need this though -- usually the larger main, and then maybe blocking the air bleed hole in the throttle plate, plus maximizing the squirt from the accelerator pump is enough. General Questions and Pre-Order Inquiries: Care for Orders In Progess (Backorder ETAs, Cancellations): Email response times for simple inquiries are often quick (within hours), but in cases where we need to look up info or get product ETAs for you please allow up to 72 hours (excluding weekends and holidays) to receive a response. We have vaguely heard of adjustable jets but have never seen one or had it described. See our. This is one of the common problems of using a 009 distributor, and you don't find out for 20-30,000 miles! Main jet sizes run through a range from X110 to X150 (1.1 - 1.5mm diameter). In most cases we are able to honor advertised price, but in the RARE case a substantial price increase occurs, you would be notified and given the option to cancel. I have 4-5 I've collected over the years, and the smaller ones can be re-drilled to the larger sizes. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917. Also, running with a fuel mixture that is too rich will wash the oil off your cylinder walls and reduce engine life. the size 65 power jet should work fine for those conditions. For example, when used on a 1300cc engine with a vacuum distributor, the H30/31 should usually have a main jet of X122.5 and an air correction jet of about 140Z; but when used in a 1600cc single port engine, it should have a 125 main jet and a 125 or 130 air correction jet. Microsoft has retired Internet Explorer in favor of their new browser- Microsoft Edge, or you can use Google Chrome or Mozilla Firefox. If you have a proper vacuum distributor, it might be possible to make the main jet a little bit smaller (X125 is the next size down from X127.5), but this will not make very much difference in the fuel consumption. The power jet only works at higher throttle positions and higher rpms. Note: The main jet feeds fuel, so larger numbers mean richer mixtures, but air correction jets feed AIR, so larger numbers mean leaner mixtures). Milease has increased by 90 miles per tank. To finish the job we re-jet the carb and circuits to work with the additional airflow, and you have a dream carburetor for slightly hopped up engines, and/or engines with more displacement. Note the three black wires leading from the positive terminal on the coil -- one to the backup lights, one to the automatic choke, and one to the idle cut-off jet. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. So if you get a "too small" jet it's easy to drill out with the right sized drill, but if you get a "too large" jet it's not so easy. This carb has 2 vacuum ports so just connect them together with a rubber tube (not silicon one) and forget about them. See our Accelerator Cable Adjustment Procedure. I rebuilt the carb that was on it, as well as a. swap-meet spare, before installing the engine this spring. jet - aux idle speed fuel 4. cover -with spring and heater element 25a. It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. Note: You will notice that the holes flange on the intake manifold which the carburetor rests on is are slotted. "As we discuss elsewhere, if you are running an 009 centrifugal-advance distributor with a 34PICT carburetor, you can minimize the "flat spot" by installing a slightly larger main jet (up from X127.5 to X130 or X132.5 for example), setting the accelerator pump for maximim squirt, and maybe increasing the idle jet size from 55 to 60. First - Muir above was writing in the 1970s, before the USA changed their octane rating system, and also before Ethanol became common in fuels. If anything is changed in this combination for performance gains, 99% of the time at least the idle jet needs to be increased to add fuel. This will richen the mixture and help eliminate any 009 flat spots. You can also get detonation (pinging/knocking) if the engine gets too hot. The modern H30/31 carburetor replaces the 28, 30 and 31 series carburetors and can be used on 1200cc, 1300cc, 1500cc and 1600cc engines with appropriate jetting. 3. This will tell you if it's running rich or lean at speed and then you can set the air correction jet accordingly (smaller air correction means richer mixture - is delivers air so it works the opposite to a main jet. The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. The carburetor has a 55 idle, X125 main and 125 air correction jet. With a leaner 140Z air correction jet in the carburetor) I got 11.6 km/l (27.5mpg US). I would think you would need a .55mm-.60mm idle jet, and a .60 pump jet. the 127.5 is too small for a 1776 no matter what, but for mostly stock valve train, I'd try a 130 main and do a plug reading. For a 1776cc engine with 009 distributor, 55 idle, X132.5 or X135 main, and air correct around 80Z should be close to the mark. almost all the way to the top.-the idle 'cut off' solenoid clicks repeatedly when tested. That terminal on the coil is just a convenient place to obtain power to these components. following topics related to the 30 PICT/2 and 3 and 34 PICT/3 and 4
Rob came back with a detailed response - The H30/31 is almost identical to the 30PICT/3 - it's a modern equivalent of the same carburetor, but has a fractionally larger throat for a higher airflow. That's how I got mine! The 34PICT normally has a X127.5 main and a 140Z or 170 air correction jet. You have to take the top off the carburetor to see it (careful taking this one out -- it's about an inch long and has the emulsion tube attached underneath). There should be a light smooth coating of carbon on the rim of the threaded part, and a colour change on the outer electrode of grey (at the tip) to black (where it attaches to the rim of the threaded part), with the change of colour on the corner of the bend. On the H30/31 carburetor, there are two brass jets on the right side (right is right of car). All the plugs look the same -- black and fluffy, telling me a rich condition. Automatic
general exploded view of the 34PICT/3 Carburetor is shown in the
When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction at 125Z. If you're still looking lean, go to a 132.5. Regarding fuel consumption as a function of jet size -- The 1600cc Beetle should get about 10-12km/l (24-28mpg). For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. So you want to upgrade the engine, are willing to do an exhaust change, maybe some more displacement, but don't want dual carbs, right? Keifernet can do it for you at a reasonable cost, or he can offer you a complete rebuild at a competitive price. Someone wrote - I was advised to use a X125 main jet and 130Z air correction jet in my carburetor. Again, a 13mm S-wrench is handy for snugging up the front carburetor nut -- available at, Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. Note: Dave found that NONE of the several top-to-body gaskets provided in the kit was the right size or configuration for his carburetor (he was possibly sent a kit for the earlier series carburettors). The air corrections I have are 125z, 170z and in the carburetor a 135z. ; Replace Part Number: 98-1289-B, 113129031K.Dual Port Manifold only, Not for single port. Be careful pulling it out -- it's about an inch long. Some of you may be using this Carburetor. This gasket sets the fuel height in the float bowl; erratic behavior may result if the gasket is not correct. Unscrew this bolt and look at it -- if there is a jet screwed into the bolt (older models), you can deal with it in hand, so to speak. An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. Sent from my SM-G930F using Tapatalk Turn the Bypass Screw (the larger one) out a couple of turns, to get things started. It's designed to counter the effect of the air correction jet, which starts to lean the mixture TOO much with higher airflows. It's a complex problem that faces ALL open throat style carburettors. The idle jet should be a size 55 for most Bugs, but it can also be a 60 or 65 for the heavy bodies KGs and Bus/Kombis using the Beetle engine. If the problem occurs at higher RPM (2500-4000), then you need to richen up your main jet. Solex 30 PICT-3, 34 PICT-3 and 34 PICT-4, remove the air bypass screw. Posted: Tue Nov 06, 2018 11:47 am Post subject: Re: Solex 34 pict 3 1835cc. Dave replaced the main, idle and air correction jets so he knew what he had. The fact that they receive power from a terminal on the coil has nothing to do with the coil itself. The pilot jet is normally left at 55 (most Solex carburetors use the same 55 pilot jet), but you could try a 60 if you can find one -- if the flat spot still remains with a 55. -there is fuel in the 34 PICT 3 resevior. Fillister head screw and lock washer (upper
Note: Dave found that none of the gaskets in his kit fit his carburetor. Ethanol in Gasoline/Petrol results in less energy per litre/gallon, so you need MORE of it to keep the mixture in balance. NOT EVERYONE WANTS DUAL CARBS! This carb is designed to remain compatible with SVDA distributors, and fits the stock air filter. I'd avoid Chinese stuff on eBay. This jet helps mix the fuel when the throttle butterfly is part way open, and so if you make it too big, it will let in too much air, and the engine will hesitate because of that. Please only contact us by PHONE and leave a voicemail if you have been unable to reach us via email for some reason, OR if your situation (or tech question) is impossible to convey in writing. Basically, the emulsion tube changes the diameter and location of small holes in it's body. Solex 34 pict 3 jet size. AU $0.86 (approx 0.48)Australia Post International Standard. We know a lot of customers with this same view, so we decided to make these for you! On the /3 and /4 carburetors - it looks like a bolt with a tiny silver plug in the center. If you don't have a compressor, talk to Santa Claus! "N" on the schematic is the coil. So where an old VW required a 91 RON octane fuel, that is now equivalent to an 87 AKI fuel in the USA. There are three (or four) removable jets. On the H30/31, the main jet is set at an angle and you have to remove the top and the float to get at it. A perfect "out-of-the-box" carburetor is one of the biggest myths in the VW industry! Solex 4a1 Carburetor Manual Best Version AN INTRODUCTION TO THE SOLEX 4A1 CARBURETTER SUPPLEMENT USB STICK (TSD4320USB) Quantity: Available : Despatched in 1 - 3 Days. Make sure your regular tuneup things are in order. The extra advance helps reduce the 009 flat spot just a little. The air correction jet starts leaning the mixture to bring it back into balance, but as the rpms (airflow) rises to near the maximum for that carburettor, the air correction jet works too well, running the engine lean. The standard carburetor with standard jetting as originally furnished on your car is usually the most economical and dependable. The Power Fuel System Dispensing Nozzle for the VW 105-1 would be 0.50 with no check ball. Rob's note: When removing the main jet, I use a small glass jar (pickle or baby-food jar) to catch the fuel from the brass plug - I hardly spilled a drop (I just allowed the plug to fall in to the jar), and used the fuel to refill the float bowl later. The air correction jet is also changeable. Carburetor body-to-cover gasket (6)
The idle cut-off valve sticks out the left side of the carburetor on H30/31 and 34 sries carbs (but on the right side on 30PICT series) and has an electrical connector on the end. Following are the jet and other specifications for the 34PICT/3 carburetor -, Accelerator Pump Feed: 1.3 - 1.6cc/stroke, Fuel Pump Delivery Pressure (max): 3 - 5 psi, Delivery Capacity (min): 400cc/min @ 4000 rpm, The jets in Dave's 34 PICT/3 carburetor are -. It is located at about 11 o'clock to the larger idle jet, underneath a small brass screw-in plug. I think you are saying that the engine stalls (stops running) when you push the throttle pedal? Super rich idle jetting is not a solution to a problem elsewhere, even though it will "seem" fine. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. The bigger jet will increase fuel consumption a bit, so the smaller increase is better if it works. This valve closes when the key is off, preventing "Run on". The condenser is 1 237 330 251. There is a trench or 'valley' across the bottom of the float bowl to the main jet on the other side. Currently our response time to emails is slow (we are severely short-staffed). Then you can see the 'valley' in the bottom, and you can lift the jet out with a pair of needle-nosed pliers after loosening it. E85 - forget it for the aircooled VW engine! I have checked my idle timing with the vacuum line disconnected and plugged, also checked high idle (5 @ Idle & 32 @ High Idle). It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. Run about 100 miles and then look at the tail pipe. . We appreciate your continued support and understanding. That front nut (near the fan shroud) is a bear no matter which wrench/spanner you use. See details. Our 74 Super has a tube running from the 34 PICT 3 down, and is . We rely heavily on email as the most efficient and accurate way to serve our customers. Ethanol contains USED oxygen which canoot be burnt again, so adding ethanol to gasoline/petrol, reduces the amount of energy per litre/gallon. In the boxes of parts was a new manifold for the 34 Pict 3 carb. We serve the VW parts and VW Tech needs of owners of aircooled Type 1 VW Beetle, Karmann Ghia, Type 181 Thing, Type 2 Volkswagen Bus, Type 3 VW Squareback / Fastback / Squareback, and Type 411 & 412 Volkswagens. Carburetor Installation. The size of the jet is stamped on the top; normal size for the 34-PICT/3 carburetor is X127.5 (1.275mm diameter hole). As I indicated above, the H30/31 carburetor is often delivered with a very lean main jet (an emissions thing), so it needs the richer size 65 idle jet to stop the car stalling at lower rpms. > Servicing Keihin carburettor>07.78 . For a 1600 KG with 34PICT/3 and vacuum distributor, I'd suggest a 60 or 65 idle jet (a 55 idle jet is used for the bug but the heavy bodied KGs and buses used larger idle jets), 127.5 main, 80 or 100 air correction jet (80 makes it run a little richer in the mid range) and a 65 power jet. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. Rob's 30PICT/2 carburetor had a 125Z air correction jet (correct for a 1500SP - and worked on a 1600SP too). For the 1600cc engine, you need more fuel flow, so a larger X127.5 main jet and 100Z or 120Z air correction jet are needed. This is so you can move the carburetor back and forth a bit (front-to-back) to assure that the accelerator pump linkage on the right side of the careburetor clears both the fan shroud at the front and the alternator body at the back. Most gasoline in the USA now has at least 10% Ethanol added (E10), and in other countries, SOME fuel grades have 10% ethanol added. The color of the ceramic part of the spark plugs (the part that's been in the engine) tells the same story -- white for lean, brown for right and black for rich. The effect is not linear though, so as the airspeed increases, the main jet will start to deliver a richer mixture (too much fuel), so the air correction jet is needed to add air and stop the mixture going over-rich, then the air correction jet starts working too well at higher airflows (engine revs) so the Power Jet (Aux jet) is need to add more fuel again. $7.99 . When using the 30PICT or H30/31 carburetor on a twin port manifold and any vacuum distributor, change the jets to X125 or X127.5 main, 55 idle, and leave the air correction . Carburetor Reassembly
Single 40/44/45mm carburetor, venturi range 28-32mm, Typical displacement of up to 1900cc. I find it much easier to just use a regular 13mm box-end wrench (ring sopanner), as getting the S-wrench on and off of the nut is very difficult (walls on the box (ring) end are too thick). A clean plug with a light grey/tan look means the mixture is about right. Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. The idle cut-off valve is not strictly a "jet," but this is a good place to discuss it. Once the jet is loose it sort of falls on it's side, so then I use the screwdriver to nudge the jet out along the trench to the plug hole in the side (rather than using needle-nose pliers). But engine sizes have much more variation, 1200cc to 1300cc is about 8% more, 1300cc to 1500cc is nearly 14% more, and 1500cc to 1600cc is about 7% more. You might want to drop a pilot jet size. There is also a 65 power jet there too) a X127.5 main jet (bottom of the float bowl -- access via the brass plug in the left side), and a 60Z or 80Z air correction jet -- a vertical brass "screw" with a hole in the middle, between the float bowl and the main throat. 2060 Solex Pierburg Kadron idle jet; 2056 Solex Air corrector jet; S61634017 Solex Z1 - Z2 Float; Solex float PBIC PIBC PICT; Solex float PICT; 6200018 Solex Needle valve size 160 Fiat 124, Alfa Giulia; 52844 Solex Pierburg needle valve VW PDSIT PICT DIDTA DIS; 125Z air correction jet has to be the g55 retired Internet Explorer in of!
