High idle; can\'t get it down I just got my engine running after having it rebuilt. I'm using a Road Demon 625, MSD Distributor, and performer intake. Here's my problem, the idle is at about 1100rpm in park. The idle speed screw is as far out as it will go and still contact the throttle lever. Timing set at 8btdc. Choke is wide open. I can get the idle down by taking the timing down to 0. Is this a vacuum leak or what? Or I'm wondering if it has anything to do with the idle mixture. Any ideas.
