    High Idle please help


    I installed a Holly 670cfm Avenger with vacuum 2nd and elec. choke on my 350hp. Ford 302. Cam spec. 212 / 220 - 112 - 498 / 512. C4 trans with B&M Holeshot converter and 3.73 gear.

    The car will not idel properly. The idle has to be set at 1400rpm while in park. Then when put in gear it almost stalls, then idles at 800 / 900rpm. I checked for vacuum leaks by spraying crab cleaner around the intake and carb base and was unable to find a leak. Ignition is msd billet distributor and 6al box. Base timing at idle is 10 degrees, with the machanical advance adding and addition 28 degrees by 2400rpms.

    Yeah man, like etbird said, don't leave us hanging.

    Other guys maybe got a similar problem, share the wealth, brotherman.
    I don't want to arrive at the pearly gates in perfect shape, rather I want to come sliding in, all burnt up, screaming "WHAT A RIDE"!
