Re: Backfire

probably a combination of the two, but i would start with the timing.

not sure why you wouldn't be able to tune an edelbrock carb...

in the front at the bottom of the carb are two screws, they adjust the idle mixture. doesn't get any easier than that.
also check the operation of your secondaries. if they are sticking open, that could cause your problem, as the mixture will be too rich for the decelerating engine.
