VW Pierburg 2E problems - Sci_kid
I have a VW Scirocco with a Pierburg 2E carb thats giving me lots of problems. Firstly it would idle very high ( about 2000 revs ), so thought the auto choke was knackered/ So fitted a manual conversion kit. It still idles high upon start up with the choke off. But when the engine temp gets to normal afyer about 5 mins the revs drop and sometimes cuts out. If I use the choke it wont start as sounds like too rich. ( correct me if I am wrong ) Apart from that annoying problem that even my garage cant fix, it runs really well. I hav e ordered a Haynes Pierburg book. Can any one help pin point the problem.
Thanks Steve

I read your post, and i remembered something similar which happened to my mates 'rocco. He replaced something called a Waxstat which cured the problem. Hope this helps.

Ok thanks guys I will deffo try changing the waxstat first. Where is this located as still waiting for my Haynes manual to come. I also blew out the mixture screw hole with my compressor and carb cleaner. It seems a little better but still reving high even when the choke is off and then after fully warm it drops down to 1000 revs, but this takes ages about 10 mins and then runs lumpy and sometimes cuts out

Try looking at http://www.edgebiz.net/pierburg2ecarb.htm

I had all sorts of advice and discovered a leaking vacuum pipe and a floating ball valve. There are photographs on the link.

If you cover no more than 100 miles per day and have easy access to a charging point at home or work, then an EV is ideal for you.

Is an electric car right for me?
