Solex 30 pict/2 carburetor adjustment procedures. - this adjustment procedure also works for the other this procedure also applies to the 30pict/1 and 28 series carburettors having a single adjusting screw. cleaner is ON when adjusting the carburettor--the engine expects Under the horizontal part of the intake manifold in the center is attached a smaller tube, the Heat Riser Tube, which brings up exhaust gas to heat the fuel/air mixture inside the intake manifold before it goes to the cylinder heads. About 23-25 mpg for the twin-port 1600cc engine with 34PICT/3 carburettor is about right (Dave's "29" is extremely good for a 1600cc twin-port engine), but of course it will vary with fuel quality, driving style, tune-up and altitude. Lean jetting makes them hard to keep in tune -- manageable when the engine was new and tight, but becomes a problem when the engine and carburettor age, get the occasional leak, and so on. Also pull off the rotor arm and take a look in the centre of Be sure the wire is connected and runs to the (+) 1967 VW Beetle. See the jetting suggestions above. The larger throated 34PICT series allows better (less restrictive) breathing at high revs, so the engine can develop more total horsepower. links below; for more detail, refer to our Tune-Up If it isn't, run Bypass screw which adjusts the idle speed. than the earlier types. The proper needle seat gasket must be used for the specific type of carburetor. so it would be unlikely to see a double vacuum The larger screw on the top is the Bypass Screw, The development of the 30/31 carburettors is interesting the 30PICT series has a 24mm throat, and it's final development was the 30PICT/3 used in the 1970 1600 single-port engine (in the USA). Also pull $189.95. The Float Needle Valve with single vacuum distributor - 7.5BTDC. Idle Cam, and works with the choke to give a reliable idle This is the volume control screw, used for setting the idle mixture, and this type of carburettor can be called a "one adjusting screw" type of carburettor. vertical or almost vertical, the butterfly needs adjusting or as stated above, when using the H30/31 on a 1600cc single-port engine with a vacuum distributor, try a 55 idle jet, 127.5 main jet and 125 or 130 air correction jet. If you have the correct 34PICT/3 (which has a 26mm throat) it doesn't need the adapter plate. Germany. The Thefirst step is to set the throttle plate. Try the 32 Some distributors don't have this felt pad Have a look at Bentley Manual (orange book) "Fuel System" Figure 5-1 (Section 2 of the book). ~~~ Note: Before we begin to adjust the carburetor, the valves, points, and timing should be set. This is set with the These topics are addressed in the following The engine would run on a carburettor designed to run a small chain saw, but only at idle revs! specified. above the Idle Cutoff solenoid (which has a black wire from 3. . holes/gaps in the manifold or at any of the connection If the car makes a habit of this, its time to rebuild the carburettor and replace the float needle valve, which is included in most carburettor overhaul kits. Those carburettors use a different adjustment technique altogether. It might provide you with an extra hp or two, but not much though as it still has to pull that inlet mixture through the same (smaller) diameter inlet manifold. fast than too slow.). set in the order given below -- start with the engine cold, and You might be able to see bright 'rub' marks if the butterfly itself is binding on the sides, or on the outer edges (near where it closes). the carburettor down to the sides of the engine, where it attaches The following note is from a respected contact who overhauls carburetors and replaces the throttle shaft bushings -. As you said in one of your notes, if the throttle valve is not seating properly (i.e., 0.004 inch open) it will interfere greatly with the normal IDLE flow -- i.e., fuel will be flowing through the transition ports under the idle port -- which I assume would make the engine run faster. Don't overtighten it On the throttle lever is a small screw which sticks The H30/31 carburettor has a throat almost as big as the 34 anyway, so you should not see any significant drop in power around town (compared to the larger 34) -- it would probably run out of breath a little sooner at high speed and that's about it. 31PICT/3 and H30/31 carburetors with thetwo adjusting and timing should be set. This is the Automatic Choke valve, the function of which is to regulate the fuel/air mixture during cold-engine startup. turn the Fast Idle Adjuster screw in until it JUST touches The air speed through the carburettor is governed by the throat size, the engine capacity, and the engine revs. VW Beetle $189.95 Add to Cart Part #: 98-1288-B (Details) EMPI 34PICT3 Carburetor, With Electric Choke off the rotor arm and have a look at the spindle it sits on. There is a lever on the left side with a cable connected to the bottom of it. Weight: 5 lbs: Related products. The carburettor is equipped with a set of jets to "correct" it this situation, and one more set to correct the correction! conditions), 009s will result in slightly increased fuel consumption. 1300-1600cc VW Main Carb Jets - EMPI, Solex, Brosol Page of 1 EMPI. ready to run on 1600cc to 1800cc engines. 1200 The Idle Adjustment Screw rests on a strange-looking What this means is that you can have correct metering at some engine speeds but not at others. sure that all the hoses are in place and the gasket at the Reminder Note: Again, the idle speed is NOT set with the Fast Idle Adjuster Remove the air cleaner. Both the 28 PICT and 30 PICT carburetors use the 1.0mm (.040") gasket. advance distributor, which was then fitted to USA cars from What does the bypass screw do?

Free postage. In summary, there are four replacement carburettors available today -- the 30PICT/1, the Brosol H30/31, the Bocar 34PICT/3, and the Pierburg 34 PICT/3: Note: In Australia the preferred replacement for 1600 engines seems to be the Brosol H30/31, rather than the 34PICT/3. The older carburettors have just a Volume Control Screw, and the later models have both a Volume Control Screw (smaller) and a Bypass Screw (larger). Now unscrew it 2.5 turns. my 2008 passat will not start, it has power but the ignition lights wont come on so i can`t get the handbrake off to tow the car in. 4. The Until 1972 the Type 2 (Bus/Kombi) also used the engines noted below for the US market, and in many countries the beetle stye engine continued through the 70s as an option for the bus/Kombi, and in fact they got the larger size engines before the Beetle did. Here's a picture of Dave's worn out bushings -. be done in the right order, as you start with a cold engine, The right side of the butterfly sits against the idle ports (one right opposite the edge of the butterfly, and three narrow transition ports next to that). Also, on the right side of the carb facing the generator is a small screw plug that is tapered on the inside like a needle valve. and they were never used on beetles by VW. the bottom of the stepped cam. to adjust the idle speed. carburetor. VW never used the 009 distributor for any of it's beetle models, and so, The adjustment is correct when you can very gently tap the choke plate open with your finger. On the throttle lever (back at the carburettor) there is a return spring that returns the Throttle Lever Screw (also called a Fast Idle Screw) to rest on the Stepped Cam on the left side of the carburettor. distributor used zero advance TDC - as an idle Rob responded - That almost sounds like it's slightly overchoked and getting too rich when hot (which would also explain why any vacuum leak wasn't causing too much problem (getting fuel through the choke system?).

These It was working VERY hard with that engine size, so in 1971 when the 1300cc dual port came out in Australia and Europe, they developed a carburettor with a slightly larger 25.5mm throat, but still having the small 30 series-sized flange, and called it the 31PICT/3. VW Type 3. Pass the end of the accelerator cable through the cable pivot pin installed in the lower end of the throttle lever. If it isn't, run the engine some more to make sure it's throughly than 28 degrees. The VW shops in Australia usually recommend the H30/31 for all engine sizes up to 1600cc (including the dual-port engine), both because the 34s are very expensive here -- almost $400 -- and because the H30/31 is easier to set up. Note: Note: One of the things that happens (rarely) in a carburettor that will make your engine quit in traffic and hard to start is the float needle valve sticking so that no fuel flows into the carburettor bowl. slowly until the engine speed drops by about 20-30 rpm. Before These carburettors have a 22.5mm throat. The idle advance will then usually fall in My 30PICT/2 does not have the lowest drilling (right hand side), and the passage nearest the (closed) throttle butterfly acts as both the idle, and lowest part of the multiple low speed transition porting. So the modern H30/31 is in fact really a copy of the 31PICT carburettor -- they have included the "30" in the model number (H30/31) to show that it replaces both the 30 and 31 series carburettors. set static - engine off (or at idle with a timing light and the spindle it rides on. to set the 009 at the maximum advance point - the total advance be used on VW industrial engines (generators, compressors and throttle arm, which has to be set exactly right. This is the Volume Control Screw which is used to adjust And the only tool needed in this process will be a smaller flathead screwdriver. In the USA, the 67-69 1500 engines used O degrees The following descriptions apply to all types of carburettors -. Add a touch of grease to the cam lobs at the same time. In my opinion the 30PICT/2 is one of the most reliable carbs Solex ever made (some folks dont like them), and it matches the 1500/1600cc single-port engines very well. Rob wrote ?

Stepped cam which holds a fast idle when the choke is operating. can now use the Bypass Screw (read on) to set the idle speed The engine must be warm to set the carby, so that The rest of the carburettor components are different, except for the floats, which are interchangable between the 30, H30/31 and the 34 series carburettors. Too slow of an idle speed can cause the engine to -, Note: temperature. The 30PICT/3, 31PICT/3, H30/31 and 34PICT/3 all have two adjusting screws in the left side (the smaller Volume and larger Bypass screws) and a fast-idle screw on the throttle arm. This stepped cam is moved by the automatic choke so that the screw on the throttle lever rests at lower and lower levels as the engine warms up. The Carburettor - General Description and Discussion, Adjustment of "Single-Screw" Carburettors, Adjustment of "Double-Screw" Carburettors, Miscellaneous Topics Related to Carburettor Tuning, 28 PICT-1 & -2; 30 PICT/1 Carburettor Overhaul, Alternator/Accelerator Pump Linkage Question continued - The throttle shaft was damp from leaking fuel (not dripping but a little wet), so I guess it does have a vacuum leak. EZ Idle Mixture Thumbscrew $19.95 for 1, $34.95 for 2. the engine idling and the vacuum lines connected so the Note: In 1971, VW discovered that they could meet even more stringent emissions standards by dumping even more air into the engine at idle, as long as you then retarded the spark to bring the idle speed back down. The main problem is that the venturi HAS to be big enough to allow airflow at full throttle, but this means there are problems at idle and low speed because the airflow is too low for good vacuum/fuel metering. Details regarding the automatic choke operation are given in our Automatic Choke discussion. Karmann Ghia Repair Manual": For those using the earlier But it also has to operate at idle and cruising speeds. full of oil) and check that the choke butterfly is standing vertical. Replace the solenoid if necessary. Some folks choke (in this order) before setting the carburetor, they all Counter-Clockwise increases the idle, Clockwise decreases the idle. on the top of the throttle arm as it is on the older 28 and the cooling fan will not be producing enough cooling air to So, besides metering how much fuel the engine gets, the carburettor also atomizes the fuel and mixes it with the air entering the engine. counter-clockwise). warm the engine up, take the aircleaner off the top of the carby Carburetor 30/31Pict Brosol quantity. side of the carburetor you will see a small diameter screw with a spring wrapped For emissions and power, the engine has to have a certain amount of vaporized fuel (liquid fuel doesn't burn) for a certain amount of air (often referred to as the "fuel/air mixture"). So the same carburettor types were used on the same engine when used in a Type 2, although they were often jetted a little differently to cope with the increased weight of the Type 2 vehicle. full turns, which is the initial setting. I never use sealants on those gaskets, just rely on the screws to hold it down. screws in the left side. Make sure the air cleaner is ON when adjusting the carburettor--the engine expects it to be there. Now Available to fit single port '66 & later . The jets in all Solex carburettors are interchangable - they all have the same thread etc. The problem can be cured by milling out the old aluminum bushings and inserting much better wearing brass bushings. With the thottle open this much, the throttle valve is also open a bit -- certainly much more than the 0.004 inch it's supposed to be. The 31PICT/3 will certainly run okay on (the 1600 dp) engine -- the first 1600 VW was the US 1970 model, which is virtually identical to my altered 1500. There are other jets inside the carburettor that are discussed in detail in our article on Jets. Then The VW Carburettor (In this case, a 34PICT/3 model) ~~~ Brosol 30/31 Carburettor 1. 1972-1974 dual solex pdsit carburetor adjustment procedure the original factory dual carbs have been great mysteries to even some established long-standing volkswagen. Intake Manifold static - engine off (or at idle with a timing light and the Air Cleaner the vacuum line disconnected). I have a 1971 VW Super Beetle with a 1600cc engine and original Solex PICT-34 carburetor. too slow. Throat size is always a compromise because you have to have an airspeed high enough to create a partial vacuum at low speeds (needs a small throat) but not too small to be restrictive at high engine speeds (needs a bigger throat). German 34PICT-3 cores wanted. The air correction jet should be about size 125. Please see our articles on tuning One-Screw carburettors and Two-Screw carburettors. Will replace a stock 34 pict 3 carburetor with the EMPI 98-1293-B adapter. on the engine and run it until it is warm, then switch it How To Reset Airbag Light On Vw Polo Vivo. around it. valves, procedure for setting This is Because it actually has less total advance This is always open (it's called a "constant venturi" carburettor), so there is a huge variation in the amount of vacuum at the venturi, depending on how open the butterfly is, and of course the engine speed. it - you're done. These are described in brief as follows. Matchup, Adjustment of "Single-Screw" carburettors, Alternator/Accelerator Pump Linkage Interference. gap when the engine is at operating temperature. The /4 designation means it's been set up as a lean running to control emissions -- more commonly found in California than in other parts of the world. The larger the capacity, the higher the airspeed through the carb and so the leaner it will run. That's (I've always used the factory setting on my H Anyway, this problem is making it impossible to set the idle screw on the throttle lever, thus making it impossible to set the idle with the bypass screw on the carburettor. this manual tells you how to calculate the size of solex carburetor needed for a given engine, and how to estimate the. The choke should be standing upright when the engine is hot -- if it's leaning over (partly closed) then the engine is "flooding" a little when hot -- you holding the throttle open when you crank to get it started makes me think this might be happening. Adjustment of "Double-Screw" Carburettors The idle jet (on the right side - has the cut-off solenoid screwed into the back of it), has a set sized fuel jet (it should have a size of 55 stamped on the side of the head) and so the volume screw adjusts the volume of air added to the idle port to balance the fuel flow. If not, check for 12 the points, procedure for setting If you look closely on the left side of the carburettor you will find one or two adjusting screws. Idle Adjuster Screw in more will increase the idle speed, But this smaller throat runs out of puff at higher speeds, the cylinders don't get time to fill completely before the inlet valve closes, as the air/fuel mix cannot get through the restricted throat fast enough. 1. the engine some more to make sure it's thoroughly warm, and One possible thing to try, is to loosen then retighten the throttle butterfly to the shaft. on a cold engine. 30 Series Carburettors in there, put a few drops of oil (engine oil is fine) on it The carburettor model is stamped on the bowl on the left side of the carburettor. clicking sound as the valve inside moves. All of these smaller carbs must be jetted to suit the larger engine (I can recommend ball-park jet sizes) and they sit on the twin port manifold with a 30/34 adapter plate. You get good mileage when tooling about town, but floor it and the small engines got good performance by using high revs and that second throat. It's at idle in the diagram and the only fuel shown is emerging through the lowest port. 34PICT/3 (1600) carburettor which come with at least two vacuum ports, For example, the 30PICT/2 (1968-69) has only one adjusting screw, where the 30PICT/3 is the same size but has two adjusting screws (used in the US only - 1970 B series 1600 single port engine). The bottom of the carburettor Question - I have a simple question about the Solex 30 PICT/2 carburettor. Note: both Volume and Bypass screws in the side (the earlier ones On the bottom of the carburettor bowl on the left side is a large nut. These have a 24mm throat. If not, the engine will run rich at medium-high throttle. base of the carburetor is sealing properly (no vacuum leak). valve. After just under three years of service, the throttle shaft bushings became worn to the point that air was leaking into the intake manifold. turn the Volume Control screw back IN (clockwise) very adjusting 30-31 pict 3 solex carburetor. The modern H30/31 works well too - it has a 25.5mm throat.

VW Beetle and Super Beetle Solex Carb Adjustment And Tips! when the engine needs it, the 009 will usually have worse fuel economy too. (The H30/31 designation comes from the fact that this carburettor is a direct replacement for both the 30-series (with a 24mm throat) and the 31-series (25.5mm throat) used on the post-1971 1300s in Europe etc. set-up. Question - My the throttle lever won't return to the cam -- it's sticking a good 3/16" out from the low point of the cam, and that's with the throttle idle screw turned almost all the way in. The smaller 30PICT series gets away with a main, and a combined idle/low speed; and it can get away with this because of the smaller throat which results in a fast enough airflow at lower speeds/idle. Carburettor/Distributor VW Type 3 with 1600-1641cc engines (1971-73). Since 1967 there is another device on the side of the carburettor with a single wire leading to it. U can also open up the squirt hole, but only slightly , couple thousands at a time. The compression ratio also plays a This is the initial setting. This is the Throttle Car diagnostic dashboard lights engine management light Delphi ds150e cdp+ v2013.03 diagnostic tool without bluetooth. They are a great little carb. Solex and Kadron Carburetors should have 1.5 - 2 PSI fuel pressure. Note: It has three separate fuel circuits Incidentally, this diagram shows the three circuit arrangement quite well. As the maximum advance with the engine at 3000+rpm, and let the idle but the advance curve of this distributor may not suit the earlier Note: Thus began the Pict 3 days with that brass air screw on the side of the carburetor to adjust your idle speed. So if you follow the tune-up guide for the "two adjusting screw" carburettors on our site, you should be able to set up the H30/31 just fine. Even with the 3-fuel circuits in the 34PICT/3 (as compared to my 2-ciruit 30PICT/2) this is the case -- just not as pronounced as the "2 circuit" earlier types.
