3. The carburetor was a little "leaky" around the shafts. Main jet should be around the 130-135 area. Pilot jet cutoff valve: 3: Carburetor upper half: 15: Gasket: 27: Circlip: 4: Float needle valve: 16: 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. I've rebuilt the carburettor, and it did not help. On the subject of ongoing jet changes, I re-installed the 60 idle jets (1600cc weber 34 ICT blah blah) and lo & behold, the light throttle and off . Run about 100 miles and then look at the tail pipe. For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. We are a "lean-staffed" small business and email care is how we are able to best take care of your aircooled parts needs! were visibly larger in the new jets than the old ones. This gasket sets the fuel height in the float bowl; erratic behavior may result if the gasket is not correct. $7.99. 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. 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. weber weber carburetors 34 ict 15290 racetep com Aug 22 2022 web 1 1 carburetor cover 31706 055 31 1 bush for fast idle control lever 12750 058 2 1 . 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? There is enough variation in fuel types, wear and tear on engine and carburetor, altitude and so on that you might need to experiment a little. The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application. Rob replaced the air correction jet with a 140Z, and at low-middle speeds there is no discernible effect. Re: 34 PICT 3 Adjustment Woes. We can only give a guide here, as engine age, type of fuel, carburetor wear, etc. The idle jet sits in a protrusion running down to the bottom of the carburettor, and the power jet sits in a protrusion running up to the top of the carburettor, so it's easy to tell which is which. Well, if the fuel/air mixture is too rich, the extra fuel will wash the film of oil off of your cylinders and wear out your pistons, cylinders, and rings quickly. A good way is to first make sure your engine is timed correctly, then wipe out the end of your exhaust tail pipe, or pipes, with a rag. Briefly, the USA has altered the way they measure the octane ratings for gasoline and now use different numbers for the same fuel, compared to the rest of the world. Dave replaced the main, idle and air correction jets so he knew what he had. More throttle does make it go away. The air correction jet has the emulsion tube attached to it -- this "foams" the fuel before it's added to the airstream in the throat. So, if you want to lean out the fuel/air mixture, you go bigger on the air jet, and vice versa. Same with the carburetors in general, so adjustments become essential. 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. Note: Regarding "drilling out" the main jet, please see our article on Tuning the 009 Distributor/
Carburetor Reassembly
The corresponding Distributor for the '67 Beetle would be the 113-905-205K. This little ball bearing MUST be in place. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. The 34PICT carburetor usually comes with a 60Z air correction jet, and we have seen them as big as 170Z. But above about 50 mph, and especially after about 60 mph, the car starts to gradually lack power, so obviously the 140Z air correction jet is a little too large -- it's running the car leaner as the speed increases. We have sold thousands of Bocar carburetors, so when we decided to offer an upgraded carb, we chose to use the Bocar 34-3. Pass the end of the accelerator cable through the cable pivot pin installed in the throttle lever. This depends on what fuel you are using to some extent (higher octane will allow more advance). (See our Automatic Choke Discussion and Adjustment Procedure.). Unsere Bestenliste Feb/2023 - Detaillierter Produktratgeber Die besten Vw aux in Bester Preis : Vergleichssieger. following diagram. If you don't have a compressor, talk to Santa Claus! Each engine is a little different, but these jets will get you "in the ball park". The back one (pilot?) The 28PCI and 28PICT carburettors were used on 1200cc and the first 1300cc engines. Soot will indicate the main jet is a little too large. Reply to Phatman. The other one (pointing straight out to the right side of the car) is the power jet, which feeds additional fuel at high throttle/high rpm. Microsoft has retired Internet Explorer in favor of their new browser- Microsoft Edge, or you can use Google Chrome or Mozilla Firefox. 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. With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. 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. ), Torque the retaining nuts on the bolts protruding through the intake manifold flange to 14 ft-lb (just a snug-and-a-tug them up tight with your 13mm box-end wrench/ring spanner). 60 day return. 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. If you live at altitudes above 5000 feet, you also have to consider that, as high altitude results in the engine running rich (less oxygen in the air but the same fuel flow through the carburetor). Then video is intended as an example.. Normally, for stock daily-driver Bugs, you will find that an idle jet size of 55-60 is right for you. 2. If it's working, you'll hear a clicking sound as the relay pulls in. 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? As indicated previously, the VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover who did lots of testing), but they are usually jetted a little leaner than that, so the X127.5 is really a minimum jetting for the 1600cc engine. It only works at full throttle and high RPMs ? Note: The number which indicates the jet size is the size of the hole in the jet in milllimeters. The trouble is, at full power/full throttle this extra air produces a slightly too-lean mixture, so there is also a separate power jet on some models which adds a little extra fuel to the full throttle airflow just to richen it up to get the mixture back into balance. I remove the top of the carburetor, then run a thin screw driver (which avoids the coil) through the plug hole to get to the jet. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. 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. Obviously it also fits all Dual Port Intake Manifolds, and we've had excellent results from these quality carburetors (Unlike the Chinese Copies!!!). The main jet can usually be removed without taking the top off the carburetor, but it's fiddly. Carburetor Cleaning
Venturi Size. Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. Over-rich mixtures will also build up deposits on your valves, heads, and piston tops. I'd avoid Chinese stuff on eBay. The H30/31 is the largest carburetor you can use with the normal single-port manifold. Turn the ignition on (but do not start the engine). Be careful pulling it out -- it's about an inch long. It's designed to counter the effect of the air correction jet, which starts to lean the mixture TOO much with higher airflows. Accelerator pump diaphragm (24)
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). 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). 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. The higher atmospheric pressure outside of the throat - in this case inside the float bowl - pushes more fuel through the jets into the airstream. If it is any lower the choke may be staying on too long, or it may be stuck on and won't open at all. IDLE JET .55 .65 .60 (d) VENTURII 40mm . Quality Parts and Tech Info for Classic Aircooled Volkswagen Enthusiasts. Venturi size refers to the narrowest channel in the carburetor throat. The UK ones I've stripped have been fitted with: Southern Carburettors or Eurocarb will sell you some. The main jet is accessed by removing the big brass bolt on the left side of the PICT carburetor, right at the bottom of the carburetor bowl. I think the original idle jet was a 50, but the replacement jet orifices (orifii?) 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. 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 air correction jet affects mostly the high rpm -- not much effect on low-middle rpm). 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. The 30PICT/3 was used on the first (single port) 1600cc in 1970 in the USA (not in other countries), and the 34PICT/3 and /4 were used on all 1600cc twin port engines from 1971 onwards. 737-144. Takes less than five minutes, then another five to put the new one in and put the top back on the carburetor. -there is fuel in the 34 PICT 3 resevior. If you try removing the idle shut-off valve and the air correction jet (the brass bolt head in between the float bowl and the main throat) and the idle jet itself, and then blast air through the passages in both directions, that might get it. 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). Do not allow cleaning solvent to come in contact with skin. However, the loss of power as you pass 60mph is noticeable with the 140Z, whereas there was lots more power for middle-higher speed acceleration with the 125Z. and 34-3 carb. In this video I share with you the Carburetor Idle setting; step by step for my 1971 VW super beetle 34 PICT - 3 Carb. Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. Main jet plug seal (15)
The question is this -- my car is failing constantly especially when I throttle in slowly; again a new set of points, cables, sparks, etc. Notify me about replies to my post Reply V. . Discussion in 'Mech Tech' started by low_light_craig, Jun 9, 2017. low_light_craig. The sizes are stamped in tiny numbers on the heads of each jet. Or should I open what I have or rob from a newer model? Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. PRICES are subject to change without obligation. So where an old VW required a 91 RON octane fuel, that is now equivalent to an 87 AKI fuel in the USA. The bigger jet will increase fuel consumption a bit, so the smaller increase is better if it works. There also is an EMPI replacement 30 Pict-1 with the Pilot Jet . 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. = 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 optimal stiochiometric (balanced) ratio is 14.5:1 -- that is, 14.5 parts air to one part fuel. You may have to get creative about how you attach so many wires to the single terminal on the coil. 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. This carb is designed to remain compatible with SVDA distributors, and fits the stock air filter. Leaks would certainly be an issue - I don't know how the threaded part would be sealed. 2 of 2 people found the following review helpful. Then if you need a fatter idle go up to 57.5, then 60. 34 pict 3 carburetor overhaul Jan 27 2023 web the proper float valve washer 4 must be used for the specific type of carburetor the 34 pict 3 carburetor uses the 0 5 mm 020 gasket a micrometer . Our test motor is a 1600cc with a 34 PICT carb and a 20% plate which has had a 28% improvement in mileage, but also runs smoother. Make sure your regular tuneup things are in order. E85 - forget it for the aircooled VW engine! Note: Normally debris (if there is any) will be located either in the air bleed at the carburetor body top, or in the access plug and jet (jet behind plug) on the right-hand side of the carburetor, above/rear the idle jet. *John Muir - How to Keep Your Volkswagen Alive -- A Manual of Step-by-Step Proceduresfor the Compleat Idiot, 1976 Edition, page 117. I've never had to do this so don't even know if it would work well. See the discussion of jetting with the 009 distributor below for needed revisions to the jetting of the 34 PICT/3 carburetor in this application. This means that the main jet is sized to the engine capacity, rather than the carburetor size, and X127.5 is the more common size for the 1600cc engine, rather than say the X125. See our Carburetor Overhaul Procedure. Hey, use the stock jet size, which is 125 for the 34 PICT-3. Obviously the 140Z jet was running the car too LEAN at speed, while the 125Z was certainly resulting in a slightly rich mix at speed. by vwlover77 Fri May 05, 2017 6:58 pm. Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. And fuels! Solex 28 PICT, 28 PICT-1, 30 PICT-1 and 30 PICT-2, remove the idle mixture screw and spring. any input would be much appreciated. Rob notes -- I have a 1500cc single port engine with it's original 30PICT/2 carburetor. jet - aux idle speed fuel 4. cover -with spring and heater element 25a. 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). We disassemble the carburetor, and bore the venturi to 28mm for more air! It's interesting to note that everything we've seen on the air correction jet talks about the effect becoming noticeable at about 4000+ RPM, but that's not the case. For example, the X130 main jet is a tad rich for the vacuum dizzy at sea level, so if the car is to be operated at a high altitude it will be running very rich, and you might get a smoother engine and less exhaust soot with an X127.5 or even an X125 main jet (the "right" size for 5000 feet altitude). Also check that the valve hasn't worked loose in the carburetor -- they do sometimes, and then work only intermittently. 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. Since Aircooled.Net has no control over product installation, we will not be held liable for any consequential costs or damages associated with products purchased. The 34 PICT-3 was used on the Volkswagen "Beetle" from 1971 until 1974. The idle cut-off valve is not strictly a "jet," but this is a good place to discuss it. With the richer 125Z air correction jet I got 11.8 km/l (27.9mpg) -- no real difference. all make a difference in how our old engines run, so you might need to experiment a little. The tiny drills are available from specialty tool shops, some large hardware shops and a few VW shops. Once you have those two sorted, then try a faster run and from 60 try flooring the throttle - if you get a good smooth response the air correction jet should be OK, but if it tends to stumble a little or feel breathless, then either the main jet is a little small or the air correction jet is a little large. Our site uses advanced code and encryption that is not supported by Microsoft's Internet Explorer Browser. If not, I find that "canned air" (like Ultra Jet or similar) works pretty well. $7.99 . 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). Milease has increased by 90 miles per tank. . ANY SINGLE THING other than stock, Berg Semi-Hemi heads, 009 distributor, extractor exhaust, etc. have the jet set at an upward angle inside the trough at the bottom of the carburetor, and so it wouldn't work with them. So, I let it warm up, and set the timing to 32 degrees full advance. In the boxes of parts was a new manifold for the 34 Pict 3 carb. The fact that they receive power from a terminal on the coil has nothing to do with the coil itself. But if you are using a cheater cam, or have a larger engine, this will likely work very well for you if you don't want the hassle of dual carbs! That will make the car run a little rich at higher speeds (less air means more fuel) but it might help. 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. Float pin retainer (7)
(The jets are made in 2.5 increments, so it goes X127.5, X130, X132.5, X135 etc. These plates provide restriction and also atomize the fuel/air mix better for greater fuel economy. The 30PICT/2 was used on the 1500cc engine (1967 to 1969 or 1970 depending on the country). We rely heavily on email as the most efficient and accurate way to serve our customers. Solex Carb Spacer for Alternator, 30 PICT Carburetors, 00-3245- The 205L number is a Bosch number, the other one is a VW number. 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 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 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. So if we say that three x's is normal full flow for that jet (stoich), then at 4000 rpm, the main jet is working more than it should so the air correction is working to pull the mixture back to normal. We are still processing and shipping orders from our warehouse as normal even while our site is offline. We sincerely appreciate your patience while we are doing these site upgrades. For the 009 distributor and the 30PICT/2 carburetor, you need a X127.5 or X130 main jet and a smaller air correction jet - about 100-110Z. (Some of this material was adapted from John Connolly's article on How to Jet Your Carburetor.). The VW 105-1 Air Correction Jet would be 125z. Aircooled.Net has them, and I think Gene Berg in the US has them too. In a VW Beetle, if you make the main jet too small, the car runs lean and this makes the engine run hotter. From memory the 205L distributor has both vacuum and centrifugal advance and should work fine. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. Rob responded - A X120 main jet would make it run leaner, and it sounds like it is too lean already. I would stick with the 34 pict 3 carb with the dual port. 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. h 34 solex 32 34 z2 manual solex phh manual solex 32 34 pdf manual manual Download PDF Solex Ddh Service Manual File Size 24 MB File Type PDF File . Once you have the jet removed, you MAY find the size stamped on the top of it -- or maybe not. Orders are processed in the order that they are received and order fulfillment time varies. I have main jets: X117.5 and X127.5 and as far as I remember currently in the carburetor is a X125. Some tests to help you determine proper jetting. It provides fuel at low medium revs too, so if it's not working you'll get a rough idle and lean mix at lower revs. Use stock vacuum line from air-intake #4 for CDI control unit. Useful experiment anyway. So there is a HUGE difference in hole size compared to the main fuel jet. Rob provided further explanation: The idle circuit is behind the main jet - the fuel flows THROUGH the main jet to get to the idle circuit. If the idle RPM peaks at 2-3 1/2 turns out, you're OK. SOLEX 34 PICT 3 Carburetor Adjustment Procedures. This helped a lot. The idle jet is on the right side and the other jet there is a power jet (which only starts working at high throttle and high rpm). Please trust that even when we can't reply to your email promptly, we are continuing to work to fulfill your Order Request as best we can, and we will contact you at any point where we have any new information that is not already posted in your online Order Progress/History area in your customer account.

Actual product may differ in appearance. 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). The ECP spec simply indicates a 34 carb jetted for use as dual carbs as opposed to the PIC or PICT which are jetted for single carb use. 2-F7 emulsion tubes for the IDF. ; Replace Part Number: 98-1289-B, 113129031K.Dual Port Manifold only, Not for single port. Be careful that you don't tighten these nuts too much -- you may strip the stud out of the base of the carburetor. My distributor is a vacuum advance (with a centrifugal?). . In the USA almost all gasoline has at least 10% Ethanol added, and in other countries SOME fuel has Ethanol added. Most carburetors come out of the box with a 55-60 idle jet. 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 have a 009 distributor (no vacuum canister on the side), the main jet should be about X130 or X132.5 and the air correction jet may be a little larger than normal -- 110Z or so -- to compensate for the dizzy's flat spot. SKU: 43-5050-7. 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. 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. On a 1600cc the main jet should be a size 127.5 (if you have a vacuum carburettor) or maybe size 130 )if you have an 009 distributor). You may want to change the jet size is accordance with your circumstance; e.g., smaller jet size at high altitude (X125 at 4000 ft.). All Solex carburetors tend to run lean at high power settings (high rpm and open throttle). The complexity of jetting is that the operating range of the carburetor's jets overlap, so a change in one area often must be accompanied by another change somewhere else, or you have problems! Let's say it works fine with the X125 main but lacks any oomph at higher speeds: try a small air correction jet - 110Z or 100Z, and see if that helps. Solex 34 pict 3 jet size. valve - idle cut off (30pict-2,3) 5. plastic cap 26. plug - av x. fuel jet 6. spring - throttle return 27. Now I have installed a newer Solex Brosol 30/31 carburetor (the Brazilian one), in good shape. For 1600cc engines, use an X130 main jet. You also set the accelerator pump for maximum stroke when using the 009. At the beginning I started to use a Solex 30 PICT-2. The idle jet should be a size 55, and power jet size 65. the size 65 power jet should work fine for those conditions. And the second issue is the presence of Ethanol (alcohol) in gasolines. Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. . Check the float valve for binding and leakage. None of these tests are definitive - just indicative. Remember on the 34PICT-3 the idle jet affects drivability and power up to about 2,000 rpm when the main jet takes over. All information should be verified prior to use. 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. CAUTION: Always wear safety classes when using cleaning solvents or compressed air. Please only continue if you are prepared to be PATIENT. The larger size 65 idle jet helped the 30PICT/3 and H30/31 carburetors overcome the very lean main jet at idle and low speeds, and thus help to reduce the "bogging" problem. It's important that you get it right. Because the aircooled engine runs hot anyway, the smaller jet in the carburettor can result in too much heat and burn the exhaust valves. Now unscrew it exactly 2-1/2 turns. ; started by low_light_craig, Jun 9, 2017. low_light_craig it run leaner, and at low-middle speeds there no.
