probably 180 deg out on timing
AnswerSounds to me that your vehicle is off time. Check the timing on it. If the timing is off it will backfire through the carb and also if it is cross wired (firing order wrong) it will backfire through the carb.
Too much fuel pressure. that typically happens when needle valve (carb pressure control) is blown off the seat.
if it is back firing out of the carb, and wont completley turn over then you may have a head gaskett problem shaunna 586 738 1782
Yes it would.
Spark plug wires incorrectly connected or it is way out of time.
yes, backfiring is always due to ignition or timing problems. Backfiring through the carb can be a symptom of a lean condition.
u have an intake valve bent or sticking open. run a compression check with all the plugs out and butterfly to carb open.

Yep.
you can check the catalytic converter it may be plugged and cause it to backfire through the carb
A fire in the carb.
