Ever heard a car backfire before?

Heard all kinds of things backfire. It's not always like a gunshot. One of my bikes likes to gently backfire through the carbs on deceleration. Need to pull do the carbs on that one, but there are fucking four of them.

We used to do this, especially with a manual transmission, going down a grade the driver would turn the key off, then turn it back on and BOOM!!
Was really fun if there were cows or sheep near the road!!

bad timing, running rich , bad float valve in the caburetor causing to much fuel
henche running rich and bad sparks too, also

I've heard it before, can be pretty loud

Yeah, like a loud fart!

Gunshots, car backfires, or firecrackers. The hood will never know.
