slow to start warm
Kafer Lover - October 14th, 2002 at 09:12 PM

Anyone know why my car (type 1, 1600 stock dual port) is slow to start when it is warm? It starts no problem when cold but if Ive been driving, stop for a little while then start it again it takes a bit of cranking before it will fire.
A little while ago I adjusted the choke to get rid of a flat spot on acceleration when cold. Are these two items related?

From the scenario you've given, it sounds a bit like it. As for what really caused your flat spot - are you running a 009? when was the carb last rebuilt? Is it difficult to set the idle?

Even when new, air-cooled VWs were rather harder to start when hot. They would always fire instantly when cold, but needed a bit of cranking when hot. I have many articles and road tests from the '60s and '70s, and most of them mention it. It seems to be one of the peculiarities of the breed.

When I put twin 40IDFs on my Beetle it improved hot starting a lot, but it was still never as good as when stone cold. My stock-carbed Kombi is the same. I've just learned to live with it and be happy that she fires instantly in the morning.

thats weird, if i stop my 1600sp for a couple of minutes and start it, it goes immediately. it takes a couple more revolutions to start when cold. odd.
