Re: Setting idle screws w vacuum gauge

Ok, I did bump up the idle scew. Don't have a tach, but i'm guessing it's close to ~700 rpm. Seemed to help.

I checked the timing and the line was to the left of the timing teeth, so I turned the dizzy a 1/2" turn to the right and the miss in the idle I was describing went away. The white line is lined up on the first tooth. I'm guessing that's ok? Going to let it cool off and see how it starts cold..
