backfires through carb
i have a 79 f 150 with a just rebuilt 351m stock distributor and a new holley 4160 carb. my problem is is that when i put it to the floor it backfires through the carb but not once it has some speed going. it also just doesnt feel like it has the power it sould have. i checked the vacume advance and initial timing every thing is fine any suggestions.
