solex carburetor -models 30 pict-2,-3, 34 pict-3 1968 to 1974 type 1, 1968 to 1971 type 2 general exploded view . Remove the brass plug with a hex head on the left of the carburetor -- bottom of the float bowl (all the fuel in the carburetor will rush out). 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. You can find 57s, etc. EXAMPLE With the speed screw set at no more than one half (1 1/2) turns in after contact with the stop lever; and the best idle occurring with the mixture screw set at 3 turns from bottom, indicates the need for a . Note: Dave found that none of the gaskets in his kit fit his carburetor. 3. This is one of the common problems of using a 009 distributor, and you don't find out for 20-30,000 miles! . Home . 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). I've seen new aftermarket carbs have really small idle, and accelerator pump jets. If the fuel/air mixture is too lean, the engine will run very hot, stumble, and misfire -- and burnt valves can be the result. Have a look at the size stamped on it too. Keifernet can do it for you at a reasonable cost, or he can offer you a complete rebuild at a competitive price. 2 of 2 people found the following review helpful.

The venturi sizes listed below are the sizes supplied by Weber in new carburetors. As a result, we have had to change our BACKORDER FULFILLMENT PROCEDURES. The carburetor idle circuit controls how much fuel you have at idle. 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. Please only continue if you are prepared to be PATIENT. The X127.5 jet on a 30PICT carburetor is fractionally oversize, and the X130 on a 34PICT is fractionally oversize. 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. Super Stock 34 PICT 3 (34-3) Carburetor, LIMITED PRODUCTION, 12V, Bocar.

So be sure to remove the gasket and store it carefully. The air correction jet is also changeable. While it is necessary to enrichen the fuel mixture when running an 009 distributor, you don't want the any richer than necessary since it will use more fuel. Contrast the Main Jet of the VW 105-1 for the '67 Beetle which would be120. and jet > size. In these later models, you can easily change the jet with a medium screwdriver either with the top of the carburetor removed or with the carburetor completely off the car. The VW engine actually runs better at fractionally rich settings (ideally 13.8:1 rather than 14.5:1 according to Bob Hoover). FreeShipping. We disassemble the carburetor, and bore the venturi to 28mm for more air! A clean plug with a light grey/tan look means the mixture is about right. 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. The timing is set ATDC. But after November 15th, all still pending backordered unshipped items will be automatically CANCELLED **(except for any special ordered drop-shipped or made/machined-to-order items). The condenser is 1 237 330 251. nomenclature and part number (referring to the exploded view). Using a new gasket, install the carburetor on the intake manifold flange. For example, a 40 IDF would need a 40 x 1.25 = 50 idle jet. 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). Turn the ignition on (but do not start the engine). I would stick with the 34 pict 3 carb with the dual port. I've used this particular carburetor with a 1600cc dual port engine and it works fine with the same main jet, but seems to like a fractionally larger X130 air correction jet (it runs a little rich with the X125 air correction jet). Main jets are primarily from 2500-4500rpms, and Air jets affect the engine from 3500/4000 on up. The speed of the engine (RPM) when it's doing this tells you which jet you need to change. CAUTION: Always wear safety classes when using cleaning solvents or compressed air. 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. 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. Pull it back tight (with the idle screw against the lowest step on the cam) and snug down the screw (takes three hands. I would think you would need a .55mm-.60mm idle jet, and a .60 pump jet. Orders are processed in the order that they are received and order fulfillment time varies. I have EMPI 34 pict 3 on GL1100 55 jet 130 jet idles 1000-1100. 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. If it's working, you'll hear a clicking sound as the relay pulls in. I have main jets: X117.5 and X127.5 and as far as I remember currently in the carburetor is a X125. Jetting was tweaked over the years for various carbs and territories. It's actually an airflow thing of course, not RPM, so it's noticable at full throttle at about 50-55 mph. I have lowered the fuel pressure down to 2.5 psi and checked the float bowl fuel height. 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. PRODUCT IMAGES are representative only. ). The Pilot Jet Valve (idle jet) would be the g55. . Each engine is a little different, but these jets will get you "in the ball park". Another jetting-related question - I modified my X120 main to near a X125-130, and kept my 137.5Z air correction jets. But engines do differ a little, and the sizes above are "ball park" figures rather than definitive. But different gears and different rpm doesn't. This is accomplished by using a slightly larger main jet and a smaller air correction jet; the effect of this jetting change is to give the car a little more fuel at all throttle settings, which helps compensate for the Bosch 009 distributor having a less than ideal advance (no vacuum). CAUTION: 3. IDLE JET .55 .65 .60 (d) VENTURII 40mm . The extra advance helps reduce the 009 flat spot just a little. Unscrew the idle jet from the carburetor and the cut-off solenoid, and blow through it. So VW chose this configuration. Make your product selections based on the PRODUCT DESCRIPTION and OPTION INFORMATION presented in the detailed product listing. The only method of getting it exact is to run the car on a dynomometer with an exhaust gas analyser in the exhaust pipe. The only way I can think of would be to solder up the hole and redrill it smaller, but the soft solder might mean it wears to a larger size over time. Carburetor Disassembly It this case you would definitely need to reduce the main jet size to say the size 122.5 or the 120. You may have to get creative about how you attach so many wires to the single terminal on the coil. Delivery: Estimated between Mon, 6 Mar and Wed, 15 Mar to 23917.

The three wires could each go up to fuse #12 individually, but that would be very inconvenient. A 44 IDF would need a 55 idle jet, and a 48 IDF would need a 60 idle jet. Great for that SLEEPER LOOK! Do not allow cleaning solvent to come in contact with skin. The 30PICT/1 carburetor was used on most 1300cc engines (about 1964 to 1967, and in some countries, up to 1970). Immediate shipment of requested products is NOT guaranteed. With the richer 125Z air correction jet I got 11.8 km/l (27.9mpg) -- no real difference. by vwlover77 Fri May 05, 2017 6:58 pm. . The air correction jet must be SMALLER to enrichen the mixture. Note: Compare the new float valve with the old one. I couldn't find it in any book. The The fuel flow through each jet is determined by the airflow which creates a low pressure area near that jet. The 30 and H30/31 carburetors were designed primarily for the 1300-1600cc single port engines, but you can get slightly better performance with the larger carburetors on a 1200cc engine, but only if they are set to run properly with the smaller engine. 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. > Servicing Keihin carburettor>07.78 . -there is fuel in the 34 PICT 3 resevior.

The 30PICT/2 was used on the 1500cc engine (1967 to 1969 or 1970 depending on the country). This jet is critical to engine flexibility and economy. You also set the accelerator pump for maximum stroke when using the 009. 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).

Note: Do not soak the choke heating element, pump diaphragm, float, vacuum diaphragm, or any other rubber or plastic parts in carburetor solvent. Then if you need a fatter idle go up to 57.5, then 60. Every engine is different, so strongly consider getting our micro sized idle jets to really dial it in. There are a few fuels which have up to 85% ethanol in them (E85). 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. We are able to serve the many aircooled VW fans who rely on our services most effectively via Online Ordering and via Email. Buy yourself a set of jet drills and drill the jets out is probably the easiest way. In the boxes of parts was a new manifold for the 34 Pict 3 carb. The air correction jet prevents the mixture going over-rich at high rpm (again, smaller numbers means richer for this jet). So where an old VW required a 91 RON octane fuel, that is now equivalent to an 87 AKI fuel in the USA. 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 . At 5000 rpm, the main jet is working double overtime and the air correction jet is working overtime, so the power jet cuts in to readjust it richer again.

Take the car for a run at a modest speed - say 35-40mph. 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. Please do NOT rely on PHOTOS while shopping as many of our products have selectable product options that may change the nature of the product being ordered compared to the representative photo. The power jet is usually a size 65. 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.

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. The sizes are stamped in tiny numbers on the heads of each jet. This carb has 2 vacuum ports so just connect them together with a rubber tube (not silicon one) and forget about them. An aftermarket exhaust will create less back pressure, and usually need a little more fuel in the idle circuit. The back one (pilot?) We did a run of these, but due to a limited supply of the quality Bocar 34-3 carbs, we do not know how long we'll have these carburetors! First - Muir above was writing in the 1970s, before the USA changed their octane rating system, and also before Ethanol became common in fuels. VW set up a vacuum advance distributor, and the stock jetting in a 34 pict 3 for a 100% stock engine. 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. valve - idle cut off (30pict-2,3) 5. plastic cap 26. plug - av x. fuel jet 6. spring - throttle return 27. Our last contact with Keith was some years ago. None of these tests are definitive - just indicative. Many thanks, John!). The last three carburetors are more sensitive, and so the lack of vacuum advance on the 009 makes more of an impact. If the problem occurs at higher RPM (2500-4000), then you need to richen up your main jet. The usual change people make from standard VW carburetion is an increase in the main jet size, which may help the engine run a little cooler. 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. 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). The use of VW, Volkswagen and any model names and numbers is for the sole purpose of description of parts application. Email care allows us to provide important service detail that can be later referenced by both the customer and our care staff. Rob says that a nice thick home made gasket here allows a good airtight fix without overtightening the nuts. 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. mains: 120, 130, 135, 145. air jets: 160, 170, 180, 185.

The 30PICT/3 and the H30/31 carburetors came with size X112 main (super lean), size 65 idle, and size 125Z air correction jets, which made them very difficult to tune. Setting the idle screws (B): Tighten the screw until it touches the carburetor lever. Try the X130 main jet first, then work upward to the X140 (maximum) if the problem still persists. If you install a single carb on GL (34/3 PICT) always keep in mind the following: 1. 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). My distributor is a vacuum advance (with a centrifugal?). 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. At the beginning I started to use a Solex 30 PICT-2. It's actually much easier to do if you remove the top of the carburetor and the float. 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. . For information -- the 1200cc engines originally came with a 28 PCI or 28 PICT carburetor, both of which have a 22mm throat. This will have the main jet supplying the fuel, and read the plug again. In other words, it's extremely crucial for in-town driving. There also is an EMPI replacement 30 Pict-1 with the Pilot Jet . following diagram. "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. Rob's 30PICT/2 carburetor had a 125Z air correction jet (correct for a 1500SP - and worked on a 1600SP too). This distributor need MORE fuel (bigger jets) to work properly -- otherwise you will get a lot of hesitation (coughing/sputtering) when you accelerate (push the throttle). The following topics are discussed in this article -. 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. Our 74 Super has a tube running from the 34 PICT 3 down, and is . You will find the Pilot Jet Valve in the same location as on the German 30 Pict-1 Carburetor.

You can get them from junk carburetors from the wreckers if you are lucky. With the air correction jet you have to go 3-4 sizes different to see a real difference, unlike the main jet where one size can make a big difference. 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. It should not need to be bigger than that with a vacuum distributor (009 distributors need richer mixtures). Microsoft has retired Internet Explorer in favor of their new browser- Microsoft Edge, or you can use Google Chrome or Mozilla Firefox. Try to use the leanest main jet you can -- too rich will only result in the cylinder oil film being diluted more, and this means higher cylinder wear. 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. 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. I have recently rebuilt a 34-PICT 3 for my bus with a S.B. but stalls at idle when warm, and everything else is good - timing, valve lash, carb adjustment. E10 usually needs a larger main jet and might also need a larger idle jet. Also if you still can't get a slow idle loose the jet a little on the other side of carb were the bypass screw is. With the larger main jet, you might also need to consider a size 50 idle jet in lieu of the normal 55. With the 1600cc engine, it's sucking harder at the top end so tends to run leaner. Air correction jets are harder to find. ANY SINGLE THING other than stock, Berg Semi-Hemi heads, 009 distributor, extractor exhaust, etc. Basically, the emulsion tube changes the diameter and location of small holes in it's body. 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. Also check that the valve hasn't worked loose in the carburetor -- they do sometimes, and then work only intermittently. the chart. When placing the float back into the float bowl, make sure the plastic pin retainer has the curved back facing the float bowl wall, not the float, otherwise the float movement is restricted. The VW 105-1 Air Correction Jet would be 125z. *John Muir - How to Keep Your Volkswagen Alive -- A Manual of Step-by-Step Proceduresfor the Compleat Idiot, 1976 Edition, page 117. We provide the classic VW hobby with tech tips, project advice, and quality parts for VW Restoration, VW Performance and Custom Aircooled VW projects. So, I let it warm up, and set the timing to 32 degrees full advance. To summarize: idle jets operate from idle to 2500-3000rpms or so. 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. 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. Note: The manuals say that you should not remove the volume control screw, as it is set at the factory. Rob responded - A X120 main jet would make it run leaner, and it sounds like it is too lean already. Located in: Braunschweig, Germany. 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. 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). They might be available individually or in a set. That means that the jetting requirement for any VW using ethanol-added gasoline/petrol is different to those using straight hydrocarbon gasoline/petrol. This is what causes the visible rich condition, and confirms the need to increase the jet size. Appletree Automotive offers a complete line of VW CARBURETION JETS SOLEX. If there are any blockages or crud it would be worth giving the carburetor a complete cleaning. $7.99 . 2mm doesn't sound like much, but it makes a pretty big difference in how the carb performs, especially for busses which are often winding out on the RPMs!

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. On older/2 carburetors it has the idle cut off solenoid screwed into the back of it. 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. Dave replaced the main, idle and air correction jets so he knew what he had. 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). The adjustable jet would work with any of the Solex carburetors which have the jet mounted horizontally inside the carburetor. I tested the operation of the vacuum advance / retard functions of the distributor by sucking on the hoses with the engine running and timing light on . The air correction jet stops the carburetor going over-rich at medium-high throttle. Make sure your regular tuneup things are in order. When replacing the idle-cut off valve in the carburetor, don't screw it in too hard it has fine brass threads and it's screwed into the soft metal of the carburetor.

The 30PICT/2 carburetor has a fuel idle cut-off in the right side of the carburetor but the 30PICT/3 and the H30/31 should have an air idle cut-off in the left side for the carburetor (same as the larger 34PICT/3) -- that was part of the change to the /3 carburetor version -- moving the idle cutoff valve to the left side. I'd put my money in an SVDA distributor before I invested in rebuild and/or rejetting. 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. ( again, SMALLER numbers means richer for this jet ) a X120 jet! Jet first, then work upward to the exploded view ) for this is...
