I'm fully stock with low miles, and can acheive great idling. The problem is top end and accel. New plugs/wires, points/condenser, coil, rebuilt carb, new rubber lines, cleaned out the fuel system from end to end. The carb has been a pain from the start due to letting the truck sit for 6 mos. at a time. I took it apart this week to stop it from sticking wide open, and it still isn't right. I get drips from under the bowl when the throttle is whacked and the motor is off. The last trip around the block seemed good on the low end, but when pressed it seemed to backfire out the carb(blowing off the air cleaner bonnet) going .vvvvvrrrrrr pop vvvvvvvrr pop vv pop vvvvvvrrrrrr. I thought I had set the timing pretty well but now I'm wondering if set by the #'s it actually is not where it wants to be. Any suggestions would great.
