    Adjustable vacuum advance

    I have the Crane Cams adjustable vacuum advance cannister on my car, along with the light advance springs.
    Has anyone played with the adjustment on theirs and found an optimal setting? I think mines at about 1-1/2 turns.

    Re: Adjustable vacuum advance

    Most times vac. advance adjustments are different between cars.
    1 1/2 sounds like a good place to start.
    Do you have a total advance limiter?
    With the lighter springs.....and total advance about 36*...AND vac. advance.......lotta stuff going on at different RPMs and vacuum loads.

    Re: Adjustable vacuum advance

    It's been a while since I've messed with one of those but I thought that the instructions said to put in a setting and advance it until you got pinging under hard acceleration/full load (like going up a long hill in high gear), then back off the adjustment until there was no pinging.
