I have just one question . When it is decelerating, only after i stomp the gas and get in to, it backfires out the tailpipe .I kind of like it like that,I guess a kinda of a redneck thing. But is it good for the engine for it to be like this ? I know it is not good for the muffler , I have split a couple in the past playing around, making it backfire .  |
Backfires usually means timing. Timing, spark plug wires on wrong, a bad power valve in the carb, the timing chain really worn, the timing off.
It could be one simple thing or a combanation of things.
