Re: Incorrect valve timing?

["Sal Guzzo" <pellom@yorku.ca>]

I'm having the same problem with my 8V rabbit. I've adjusted the fuel
mixture by richening it and it seems as though on start up (when it's cold),
the idle is better. Mind you, I had a vacuum leak and I adjusted both the
idle (off the TB) as well as the fuel mixture. I will know if it's perfect
tomorrow morning as I let it kewl down for the night. I'll keep ya posted.
