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.
Spark plug wires incorrectly connected or it is way out of time.
Too much fuel pressure. that typically happens when needle valve (carb pressure control) is blown off the seat.
Yep.
you can check the catalytic converter it may be plugged and cause it to backfire through the carb
A fire in the carb.
As with any engine, timing, and also carb problems.
after rebuiling carb jet have 2 b adjusted, check ur timing also If you have any exhaust leaks close to the engine it will promote backfires.
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.
Yes it would.
