Pierburg -> Weber. www.???weber???.com

I have 1.6 liter '87 carb (Pierburg 1b2) 316 BMW. My problem was (or still is, temperature is higher now) stalling while warming up. When needle on temp gauge leaves blue area engine rpm would go low ~500 - 600 rpm, and engine will sometimes die. I tried to fix the problem by checking all vacuum operated devices (on the carb, distributor), looking for the vacuum leaks, adjusting valve clearance's, checking rotor arm and cap, HT leads, changing sparkplugs, and testing all that I could on the carb (from the Haynes manual and Pierburg manual for 1B2). And all looked OK.

So I went to BMW dealership. They did all I did, and found all to be OK, but they had advantage - exhaust analyzer. So now after finetuning things look better.

But I noticed that engine shakes at idle. Not constantly, but works OK for

10 or 15 or 20 sec, than a little shake, and so on.

I had a lot of suggestions on NG to bin Pierburg and get a Weber carb. Where is Weber factory? Does anyone knew their web address? I would like to find local Weber dealer (I am not in UK).

Spain IIRC. I've also heard that it's shut down as all the race and rally boys are going for throttle bodies these days. There's still stock about though. Other than that, there's Ebay. And webers were fitted to escorts. Might be easiest to find a weber on a scrap car then sort the jets and other bits and bobs out.

OTOH, do these have an autochoke? These famously pack up a lot on the Golfs fitted with this carb. TBH I'd be happy with a bit of rough idling and not lash out the extra cash to put a weber on it. Unless it's costing a small fortune in juice. If it's really bothering you, I'd buy an injection model...

Pierburgs are the work of the devil. Many older Golfs are scrapped because of a knackered Pierburg.

You may need to do a bit of hacking around with mounting plates, but this would almost certainly bolt on without pissing about with rejetting:

Loads of 'em around in scrap yards, too.

Not where I am.

Yes Pierburg 1B2 has autochoke. Electric. And some other device (not connected to choke), similar to waxstat with coolant running around it. Quite complicated. I found one local Weber shop, they promiced too check if they can get Weber kit for my BMW.

I have LPG conversion, so I do not spend a lot for gasoline. But I am unable to determine if it's carb that is my problem or iginition, since this carb is full of fuel and air passages with systems regulating mixture. This car has only 30000 miles on the clock, I am the first owner, and do not want to trade it.
