Carb prob now sorted with a twin webber conversion, cheers!

My 1.8 1990 Cab is still running the original Auto choke/carb, and when started will quickly rise to 2000rpm and does not go back down. The only way to get the revs down is change gear and let the engine slow it down.

When I go to turn off the engine it stops, fires up again, struggles and then dies. Then it won't start at all.

Leave it say 3-5 mins and the engine starts beautifully and idles at a perfect 900-950rpm!

The car also seems a little sluggish on take off, but once the initial pull is there it flies along.

After driving it with normal tickover it stops fine.

There is NO air leaks, (have just had this checked)

Any idea's?

Cheers, Sooty.

I'd guess this is something to do with the auto choke, but have no experience of them so can't be much more use

Not something silly like an arm sticking that just needs a little oil?

Still sounds like an air leak to me; It runs faster than it should and when you shut it down it runs on.

Either that or an internal carb fault…air leaks still my favourite.

Local mechanic sprayed some stuff on and around it and said "def no air leaks there!"

Dosent have to leak air in thru the carb tho…can be a split vac hose allowing it in or air sneaking in past a damaged manifold gasket.

Id suggest you have a really close look at all the small bore vacuum lines and see if any are split, chafed, cracked or otherwise holed or hanging off.
They usually split where theyre pushed on to the carb or other vacuum ports and they can allow air in even tho visually (just a brief glance) would appear to show otherwise.

I used to see so many of these kinds of easy fix faults.

Have a nosey and see what you can find.  8)

many thanks....

sounds liek a waxstat and/or 3/4 point unit failure. check the 2e2 faq for loads of info on how to check these carbs for faults & fix em.

Ha… the mechanic said something about wax type stuff being inside and maybe that was the problem….

Will look at FAQ…. cheers.

Well….. Got sick of the revving at 2300 rpm at idle and not turning off, so went and bought a twin webber conversion kit. As I took the carb off it almost came off anyway! The rubber plate thing on top of the manifold like a mounting plate was totally perished! Nothing left really!
So do I get new one and put old Carb back on? No… put the twin Webber on.
I know it's nothing much to some of you guys but WOW! What a difference my car is! Like a new engine! And ALOT quicker! weeeeee!

Wife not driven it but i'm sure she'll be pleased.

So now I have a Carb (Auto choke) that I don't know if its 100% ok or not! But it's on E-Bay with my other golf bits, my user name H7AKE.

Cheers for all the help guys!

how much did you pay for your weber? and where did you get it?
I'm asuming you got a single (as in one piece) twin choke weber carb.

yeh it's a one piece thing…. paid ?50 for it! and it was brand new! Bargain me thinks, as the car is transformed. The pick up acceleration is 5x better maybe more. Very very impressed.

that is a good deal, i've just paid nearly 5 times that for one.

My good!
