Gold 1.8 Driver, 91 model, Where is the idle screw??

Mk3 or 4?

We'll need to know that for starters! (i.e. Pierburg or single point injection)

Tim..

Mk3 or 4??????? 1991??????

Yes could be both at that year.

Tim..

And even so, I don't think the first Mk3s came about until 1992. 1991 is H/J reg changeover year - as in only the very early J reg ones would be 91 registered - I'm sure the Mk3 started later than that.

Tim (remove obvious) ( snipped-for-privacy@NObtinternetSPAM.com) gurgled happily, sounding much like they were saying :

Mk 2 or 3, surely?

Its a Mk2 with a carb..

Yes, its a J reg, Mk2..

Take it to someone who knows what they're doing.

Golfs and Pierburg carbs are a black art.

It has a large nut on the side of the carb which adjusts the idle speed, but first check that the choke is going off and that the throttle cable has slack and that the engine gets to normal temp.

Thanks, I will have a look.. Would it be in the side where the cable is connected?

I am going to check the choke operation this morning and I did feel some slack (maybe too much) in the cable..

The temperature is fine, I just put a new thermostat in yesterday but finished too late to set the idle etc.. Whoever had the car before obviously decided that cars don't need thermostats so when I opened up the housing it was empty.. Thats scary!!..

I had a good poke around this morning.. Couldn't see anything that looked like an idle screw/bolt but what I have found is the rubber flange that sits between the carp and the manifold look like it has a crack in it which obviously means an air leak and so a high idle..

Looks like it going to be a real bitch to get the carb off because its so tight in there and I can't really even see the mounting bolts..

Is there some trick to getting these carbs off??

Thanks

make sure the rubber is split by spraying some carb cleaner or wd40 around the split with the engine idling, if it changes speed you know it is leaking, IIRC the carb bolts on from the top ie long bolts right through.

Is the choke coming off?

That's your problem mate, you've got a fish blocking the inlet up.

The message from "SimonJ" contains these words:

Probably left it in the carp ark too long.

LOL.. Really should learn to re-read my posts..

Yes, its looks like its coming off fine..

Thanks I will have a look at that..
