Carburetor Reassembly The idle jet is usually a size 55 (when the main jet is normally a size X125 or X127.5) but it might be a size 65 if the main jet is a X122.5 or smaller. "Lean" means less fuel with the same amount of air, and of course "rich" is the opposite. Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. Screw it in GENTLY until it bottoms. Dave replaced the main, idle and air correction jets so he knew what he had. Main jet sizes run through a range from X110 to X150 (1.1 - 1.5mm diameter). You also set the accelerator pump for maximum stroke when using the 009. Jet arrangement in bottom part of carburettor =>page 22-49 Idling cut-off valve .

Contrast the Main Jet of the VW 105-1 for the '67 Beetle which would be120. There is an pilot (idle) jet on all carburetors too - these are normally left at 55 for most carburetors (28, 30, H30/31 and 34 series), on any engine size (since it's only feeding the engine at small throttle settings anyway). If the color of the deposit is tan or brown, you are running too lean and the main jet size should be increased. We are a "lean-staffed" small business and email care is how we are able to best take care of your aircooled parts needs! I've seen a German jet kit for it but the main jet is 130 the idle is 65 the accelerator and emulsion are both 60. Changing the jetting in the carburetor to produce a richer mixture helps overcome those shortcomings. 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. If you are using a 009 distributor with a 30PICT carburetor on a 1600 cc DP manifold, the main jet should be X130 or X132.5 and the air correction reduced to about 100Z. Except for the fact that it won't idle! VW set up a vacuum advance distributor, and the stock jetting in a 34 pict 3 for a 100% stock engine. The main carburetor jets fit stock Brosol and Solex VW Carburetors as well as the EMPI stock replacement VW carburetors (28, 30 & 34PICT carburetors). vegas following diagram. Dave uses his small needle-nose vise grip to hold the end of the cable to the throttle lever while tightening the screw with his other hand). With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. Do you know what size high speed jet you have? Adjustment directions are given below. Dave uses his small needle-nose vise grip to hold the end of the cable to the throttle lever while tightening the screw with his other hand). Note: You will be removing a number of small parts in this process; hopefully "stow them in a safe place" goes without saying. This will richen the mixture and help eliminate any 009 flat spots. Could you help me with the jetting? Bentley (page 20 of the 'fuel' section -- table of 'carburetor setting and jets') says the X130 was normal for '71-'72 34PICTs, and X127.5 was normal for '73-'74s (non-California models). In other words, it's extremely crucial for in-town driving. by vwlover77 Fri May 05, 2017 6:58 pm.

Dave jetted his new carburetor as follows: main jet - X130; idle jet - 55; air correction jet - 80Z. We have heard it said that the X130 (or X127.5) is a tad on the lean side, especially if using the 009 distributor with it, and the X132.5 gives a fractionally rich mix (which VWs have always liked better than lean). Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Rob replaced the air correction jet with a 140Z, and at low-middle speeds there is no discernible effect. In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. A loss of power is the result -- about 58hp instead of 60hp. Our ability to respond to emails is greatly hampered by being under-staffed during this downsize transition time. Seller pays for return postage. My distributor is a vacuum advance (with a centrifugal?). The standard jetting that the 30PICT/1 & 2 carburetors came with is size X122.5 or X125 main, size 55 idle, and size 125Z air correction jets. 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 .

Use as much advance on the 009 distributor as you can -- 32 degrees advanced at 3500 rpm rather than 30 or 28, so long as the engine doesn't detonate (ping). And I have the by pass air cut off valve (12V thing) on the left side (as same as on the 30 PICT-3, which I have seen on pictures in books, but the by pass air cut of valve were always shown on the right side). *** Supply-chain disruptions have hampered our ability to acquire/restock items reliably, and a lack of backorder ETA information is the frustrating "new normal" for our hobby. 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. 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.

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. Nomenclature And we will continue responding to emails through until early March 2023 because we are wholly committed to resolving any other issues that may arise from previous sales. Now unscrew it exactly 2-1/2 turns. The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. 34 PICT Carburetor Combination, Automatic Choke Discussion and Adjustment Procedure. 1975 GL1000 Restored (sold) 1983 GL1100 Custom (sold . Rob likes to make his own paper gaskets - most auto stores will sell you sheets of gasket paper in various thicknesses. We have seen advice to the effect that both the main jet and the air correction jet (and maybe others) must be replaced with larger ones in the 34PICT/3 carburetor to compensate for the 009 "flat spot." 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.

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. In addition, if you have a problem with a 55/60 idle jet, and you have the right main jet, and still have a hesitation regardless of accelerator pump adjustment, you need to play with your idle air bleed (what the fuel from the idle jet mixes with). The extra advance helps reduce the 009 flat spot just a little. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. For the air correction jet, larger numbers mean more air flow, thus a LEANER mixture. Nothing is exactly that linear of course as the jets are all different sizes, but maybe it helps visualise the problem of keeping the fuel flow balanced at different rpm/airflows. The air correction jet must be SMALLER to enrichen the mixture. (You must log in or sign up to reply here. All suggestions here are just that - suggestions. See our Accelerator Cable Adjustment Procedure. The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application.

The idle jet is normally a little larger when used with the heavy bodied Type 2 and Karmann Ghias - in a Bug you usually use a 55, for a Type 2 or Karmann Ghia use a 60 or 65this gives you a little more power at low and medium speeds. These carburetors come jetted "generally", and will bolt on and run. The air correction jet doesn't affect idling very much since it helps control the mixture at higher rpms, but worth a look to see if you have a fuel blockage problem in the carburetor. I don't think you'd honestly notice the difference. It only works at full throttle and high RPMs ? In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. the size 65 power jet should work fine for those conditions. The venturi sizes listed below are the sizes supplied by Weber in new carburetors. If it's not, the float bowl will overfill through the bowl vent down the throat of the carburetor, causing the fuel/air mixture to be WAY too rich - and of course the exhaust will spew out a lot of black smoke and the engine will not run. Please only continue if you are prepared to be PATIENT. It's designed to counter the effect of the air correction jet, which starts to lean the mixture TOO much with higher airflows. If you can't find one at about 125-130Z, try a smaller one, say 110Z. Recommended sizes are given in this article. To explain, the main jet supplies the fuel, and it supplies too much as the rpms increase (a function of the increasing vacuum in the main venturi). Note: Dave found that none of the gaskets in his kit fit his carburetor. This carb is designed to remain compatible with SVDA distributors, and fits the stock air filter. Be sure to check your engine's fuel pressure and ignition system. 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 performance would tell you some of the answer, but inexperienced folks using one might get themselves into trouble where using a fixed (normal) jet and changing it for a larger or smaller one would give you a known change in fuel flow. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. You will see a black wire coming into the positive terminal on the coil from fuse #12, which receives power from the ignition switch, so the valve opens whenever the ignition is on, allowing the idle fuel to flow. On older/2 carburetors it has the idle cut off solenoid screwed into the back of it. 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. It should not need to be bigger than that with a vacuum distributor (009 distributors need richer mixtures). If that's the case you need to make sure the idle cut-off solenoid is working (a nice click when you touch the wire on the connector) and that the idle jet (which it screws into) is not blocked. The numbers are: 231 168 015, and 043 905 205 L in the second line. 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 smaller jets WILL NOT work with the 009 distributor. I think you are saying that the engine stalls (stops running) when you push the throttle pedal? In both cases, when running the 009 distributor, set the accelerator pump for maximum squirt. 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; In either case, spending the time to properly jet your carburetor is a very worthwhile task.

Golf Mk1 > Volkswagen Workshop Manuals > Power unit > 34 PICT, Keihin carburettor and ignition system > Mixture preparation carb. 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. There are a few fuels which have up to 85% ethanol in them (E85). 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. The stock carb has a 26mm venturi. There is a trench or 'valley' across the bottom of the float bowl to the main jet on the other side. Note: Regarding "drilling out" the main jet, please see our article on Tuning the 009 Distributor/ Assuming a vacuum distributor, the 34PICT/3 carburetor is usually jetted with a X127.5 main jet, and 100Z -120Z air correction jet. First - Muir above was writing in the 1970s, before the USA changed their octane rating system, and also before Ethanol became common in fuels. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. 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. If the jets are screw in to tight that will cause high idle. If it has the small main jet, then you'll get better performance and easier tune-ups if you change it to a size X125 (for 1200/1300/1500cc engines) or a size X127.5 (for 1600cc engines) and change the idle jet to a size 55. We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. With the richer 125Z air correction jet I got 11.8 km/l (27.9mpg) -- no real difference. Lastly, you have emulsion tubes to change "where" it's rich, lean, etc. Details. Carburetor body-to-cover gasket (6) Idle Shut Off Valve, 34-3, 34-4, and 34 PDSIT 2/3 Carburetors, 049-129-412C Is the valve on the side of the carburetor that provides air to the idle circuit. Others might find that the 30 sized carburetor on a 1600cc engine works better with a larger X127.5 main jet. The following topics are discussed in this article -. 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. Ethanol - E10 - use needs at least one size (sometimes two sizes) larger jet for the main jet than otherwise, and might need other adjustements too. These are setup for 12V electrics, and include the idle shut off valve. The speed of the engine (RPM) when it's doing this tells you which jet you need to change. That terminal on the coil is just a convenient place to obtain power to these components. 3. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. The condenser is 1 237 330 251. Then remove a spark plug and read it (see our Spark Plug Reading Guide). Size 24 MB File Type PDF File Get free Mikuni Solex Service Manual Solex .

The /4 version was used in California and had additional features to reduce emissions. 55 idle, 127.5 main. 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. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. A detailed question: I have a Type 2 Bus, with a 1600cc single-port engine. Air correction 75 to 125 and these are changed. Where the early style carburettor has the idle cut-off solenoid on the RIGHT side of the carburettor, that solenoid sits in the back of the idle jet. There also is an EMPI replacement 30 Pict-1 with the Pilot Jet . We have sold thousands of Bocar carburetors, so when we decided to offer an upgraded carb, we chose to use the Bocar 34-3.

Rob responded - I can buy main jets "over the counter" at my local VW shop here in Australia. A sooty plug means the idle jet might be a little large. I'd go for a 130 main. The power jet is needed to correct a tendency for the air correction jet to work TOO well at max airflow - it leans the mixture off too much and the power jet corrects this. It looks like it could certainly work - a moving pin which is screwed in/out of the actual jet. Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not.
