Golf Mk2 Driver 1.8 '91 - Desperate help needed!

[KRdubber]

If it starts fine with the airbox off take it down the road and see if it runs ok , provided you dont leave it like that you wont get any crap in the carb its ok just to test it.If it runs ok then it has to be a restriction in the air intake but have you not checked all that?

It revs up fine all day long with the air box on, though. Just dies under load.

Sorry I've not actually tried any of this yet. Just trying to come up with every possibility so when I eventually go home at the end of March I can do it all then. Cheers for all the help so far.

Still smells like carb icing to me.

Not in this weather. Get it to a rolling road where they know how to setup a carb, if somethings up with your hardware the r/r session will highlight it to the operator, if not its just general carb settings, which are crucial to its running

For the price and hassle of a bit of pipe you might aswell fit the hot air pipe just to rule it out.
can you tell us exactly what you have checked please?
If you say the ignition system is ok then i would still go with the carb being clogged up.
I assume you drove it without the airbox on and it is still the same?

Car wqs running fine before all this though. Really pleased with how responsive it was. Surely ita set up wouldnt change over night.

Anyone have a theory behind the loss of idle and choke speeds. Sits at about 700 and 1200 instead of 1000 and 2000ish.

[KRdubber]

tell me what have you checked on the engine?

[Billy213]

As of yet, nothing really. Cleaned the carb jets the best I could.

Everything I've done has been electrical which is just to get it back into a position where it will actually start. Now I've gone full circle and ended up in the same position I was in at the start of the year.

And why not in this weather ? carb icing happens in the damp not the cold...

My Golf used to get it worse on warm humid days... until I got a new air intake pipe

I used to get carb icing on my 1.3.  Wasn't necessarily down to the weather.  Sometimes happend when I was at motorway speeds - all that cold air rushing in.
