I think the ignition is drawing power from the brake lights. Wire the brake lights to the hot side of the coil. I"M KIDDING!!!! The low vacuum theory is sound with a wild cam. I have drilled very small holes in the butterfly's so they have to close to reach an idle. This is the only way to get the idle transfer circuit to work with a low vacuum cam. That's the little slot in the venturi beside the butterfly. Check the position of the butterflys with the car off and the choke open (hot) and the throttle back to the idle stop. Good luck
