Vacuum Tuning

AJ,

Thx for the feedback. Actually I am at 22 * initial. Mayby too much. You explained the fluctuation well so I will not concern my self with that. The reason initial may be a bit high is because engine seems a bit rough even above idle until I get to about 1700 RPM. I also need to check my distributer to make sure no advance in coming in until past that point. In a former thread I explained how I made the mechanical advance adjustable. Presently it max's at 7* on the rotor or 14* crank.

This is idle/off idle transion , circuits. How do you ,adjust idle speed & mixture? That affects everything, up to 2500-3000 on a street ride.
