Carb model not idling?

Hey guys, first of all, just wanna say, I love your forums, really helpful and informative. Im from South Africa, and theres not alot of support for the older e30s here.

So, I need to know, I have the early model m10 Carb model e30 316, and my idle is also all over the place, around 900-1200 rpm, and this persists into driving as well, in 5th at 3000 i get a bit of jerking, and it seems to run very rich. Worse news is, this week she suddenly decided she doesnt want to idle at all, and will only keep going if i repeatedly give her gas.

The pierburg carb wasnt on the car when I bought it, instead it a vw jetta carb, but cheap pirate, not original.

My question is 2 fold,
1- should I get a weber and if so which size? and 2, what can I do to fix the idle?

I have replaced the timing chain and sprockets, and that theres the usual tappet tap but not too loud and however it seems to be all fine except the idle.

Thanks,
Rolomiester

You're probably going to need a rebuilt carb. Give our parts specialists a call at 1-888-280-7799 and they can help figure out which part or repair kit you need.
