Re: Mystery to Me !
Pop out the muffler means unburned gas, so that's probably an electrical problem. A pop from the carb-intake usually means a timing problem, maybe from loose points or something in the distributor.
Just intermittent misses could be fuel delivery.

Re: Mystery to Me !
last time i had any kinda back fires through the exhaust my resistor wire was grounding out to the exhaust. check your resistor wire and see if its touching the exhaust(the wire running from the post on the starter furthest away from the block)
