    I've decided to start a new thread as my previous posts were added to someone elses and we've moved away from the original topic of head gaskets.

    I have a 1988 Golf Tour with 1.8 GU engine and the original 2E2 carb.
    After lots of effort it is actually running pretty good.
    I have had numerous problems getting the carb to run stable.
    The symptoms ranged from, fast idle/ running on/ stalling/juddering when warming up/high petrol consumption etc. most of which can be caused by the automatic choke body not getting sufficiently hot enough to make the waxstat respond and bring down the revs to the prescribed 800rpm.
    Other problems are leaky pipes for various vacuum reliant functions.
    For a long time I had a 'dead spot' symptom, in my opinion one of the most annoying and irritating of problems. The one that lets you down when pulling away on a traffic island for e.g.
    Also, if you slightly revved the engine repeatedly during ticking over, the engine would stall completely as if flooded .
    I couldn't find a way to remedy this fault other than a slight improvement when cleaning the plugs. In my frustration I took the car to a local VW specialist centre and the chap there took me for a drive in it, only to ask me "well what's wrong with that mate, it's going perfectly!"
    Problem was, he drove the car so slowly and carefully that the dead spot did not occur and the chap just would not accept that there was a problem.
    Being dissatisfied with this outcome I decided to completely strip the carb and replace any necessary parts with a 2E2 service kit.
    After taking the top off the carb I revealed the culprit. There is a part called the accelerator pump injection nozzle which squirts fuel down into the primary port. This nozzle is supposed to have a ball bearing in it but it was missing and so fuel would pour out of the hole left by the missing ball bearing when the accelerator was operated. I managed to find another complete nozzle from a carb off a 1.6 engine. I fitted this on and bingo, we were back in business. I don't know if the nozzle jet is the same size as the original or not, but it has certainly stopped the engine from flooding and stalling. For a long time the 'dead spot' went away, but hey, guess what? It's back!
    Anyone got any ideas?

    I would look on ebay for a rebuilt/2nd hand Webber 32/34 carburettor as the Pierburg 2E2 one fitted on the golf was unreliable(read notoriously *****)...

    I forgot to add that I'm not ready to go down the Webber route yet. But appreciate your input.

    I have purchased a used one just in case I submit. But at present I am determined to beat the beast and keep the car original.

    It's gotta be made to ave it!

    You're a persistant man!
    I've thrown in the towel with my 2E2. So ordering a Weber after pay day. As the car's only done 95k I feel it could be money well spent to prolong the life of the engine. As I have to rev it hard to start it and I think this must be cripplng for the engine...

    Thanks for your response.

    Sorry to hear your about to pester 200ish on a replacement carburettor.

    I reckon the 2E2 is fantastic when working right.
    It's not the actual carb that is at fault half the time it's all the supply lines i.e. sufficient vacuum with no perished pipes, reliable 12 volt power supply to all components and constant hot running water to pamper the automatic choke unit.
    In fact servicing a 2E2, to quote Charlie Higson, "is like making love to a beautiful woman".

    I've been trying to cure the flat spot problem and to make the engine run more stable at tick over.
    I've had a good day today. I broke off one of those small plastic tubes on the main non-return valve coming from the brake servo, a long time ago and patched it up by using a screw to blank off the hole.
    I managed to find a replacement one from a scrap yard and fitted it on today. Not an easy job because the vacuum pipe fits into the brake servo right behind the brake fluid reservoir and it took an awful lot of pressure to remove it.
    Fitting the replacement went a lot easier thanks to a dab of Vaseline.
    Also replaced the flange gasket that the carb sits on. The old one seemed to be wet with fuel even after tightening the carb mounting bolts.
    Anyway it runs a little slow at tick-over when fully warmed up, but I think a definite improvement all round.
    Flat spot is less pronounced and engine generally more stable.
    Now I need to work on getting the secondary throttle to work efficiently. I noticed when I lifted the carb off that the port looked quite black and oily where the throttle flap closes.
    Any ideas anyone?

    I wish I had the know-how of how to strip down a carb. I imagine it would save me a few quid! I've had my girlfriends dad adjust the idle speed and tweak the jetting, but to no avail. I've been trying Redex persistantly since owning the car (Nov 07) to see if it would make a difference over time, but the results are negligeable. So I thought, as I can afford one now, its time to convert.

    I know 2nd hand Webers are cheaper, but as my car has only done so few miles, I feel I should splash out on a new one and hope the car lasts another 100k!

    towcestervag's offer of the workshop manual will probably be a mighty useful one - Dad has been looking at it and thinks he will tackle Rolf's carb when he (Dad, not Rolf) comes back from Germany. It's really well detailed.

    I've not really come across the problem you’re having with your car. I appreciate what your doing but just out of interest, when the 2E2 carbs play up, it's usually that they are revving to high on start-up.
    Yours seems to have the opposite symptom, that it won't run unless revved.
    Is the carb dirty when you remove the air box and look down into the ports?
    Sounds like it’s blocked up to me. Is there any mayonnaise in side the air box or oil trickling through the breather pipe?

    Was that post directed at me?
    Because if so, I have checked down the ports and it seems clear enough. The butterfly valve is also free to move.
    I have often toyed with the idea of pouring Redex directly into the carb whilst the engine is running as the bottle suggests, but some of my workmates have warned me that I may lose my eyebrows! So I'm too scared to try it lol!
    All the pipes appear clear too, and all vacuum hoses are intact. I can only assume that my choke is naffed.
