Hello! I have 1.3 golf 2 with pierburg 2e carburetor. The car starts well with cold engine but the revs start up between 2000 to 3000 rpm and when it gets warm (when staying still) then rpm starts falling to 1300-1500 and then instantly go up to 2000 and constantly switching in every 1-2 second until it stalls like in about 5 minute at most. I can instantly start engine again and hold the gas a little bit to hold revs on 1500 but when releasing gas, engine stalls. When I start driving and the engine gets warm then it stalls when pressing clutch. While still moving and releasing clutch, car starts up again, just wont idle and dies under 1500 rpm. It has changed carburetor gasket between carb and manifold. New air filter, spark plugs, vacuum hoses. Carburetor is also cleaned a bit time ago and the car has been driver about 150km in last few month. So may it be something happening with waxstat? Or the mixture screw position? Local garage had no idea what to do with carburetor and they were not ready to take a look on it. Any ideas?
The version of Pierburg 2e fitted to the 1.3 engines is known as 2e3, which is quite different to the 2e2 fitted to the 1.6/1.8 engines. The main castings are the same, but lots of the bolt-on bits are different. There is no waxstat on the 2e3 for example. Most of what I know about the 2e3 carb is in this thread from 2010. There's a Romanian guy who uses the name 'masster' on here and on Briskoda.net who has done a fair amount of work to try to understand everything about the 2e3. Try searching for posts by that username on here and Briskoda, if you can't find anything that solves your problem on the thread I linked above. Good luck with it, and please do let us know if you find what's wrong and how to fix it.
Well, specialist will watch my car in a few days. So far nothing but will see soon. I will write what was wrong or did not workthen.
Turned out that that one of the flaps or whatever it is inside the carburetor, is really damaged. Also gasket between manifold and carburetor was broken, pulldown choke is not working, and few other minor issues what we weren't be able to fix yet. But in the end right now the engine is running decent, idle is about 1000-1300 but its the best so far. Starts with cold. Only few times the engine wants to stall but so far decent. I will try to find the right missing pieces for the carb and put it all together at some point but in the end I think it may be good to buy in better condition carb or even newer.
Anyone know how I would get to know what carburetor exactly it is. On carb it says pierburg 2E made in germany. I would like to know if pierburg 2E2 would fit to my engine.
If it's the factory-original carb it will be a 2E3, but you should see a Pierburg and a VW group part number very near to where you're seeing 2E. Either of those would allow Google to fully identify it for you. I can't remember if there's 'gubbins' in the way of seeing that part of the casting where all that info is stamped? Might need a bit of cleaning up to see all the info? 2E2 doesn't naturally go with your engine, the jets wouldn't be sized right, and some of them aren't removable without serious work. There is a Weber alternative carb that does suit the 1.3s; DMTR rings a bell.
