I will. I also am going to try to run the idle a bit richer. Maybe I was shooting for to lean at idle and with the over lap in the cam it just might work? I should be able to play with it again this weekend. Thank you everyone for your suggestions
You mentioned changing power valve but then you say it won't affect idle. I had a small off idle lean surge and a carb rebuilder recommend the 8.5 since my cruise vaccum was 14. I can try the a 4.5 I have one easy enough to do.
okay hear goes. Tee' d in a fuel/vacuum gauge that I had and it ran between 5.5 and 6 at all times. Hot, cold idle and off idle. The other gauge oiled filled on the fuel line reads zero when hot, it has to be wrong.
