Needs a tune up
Probably. Backfiring is a symptom of a lean condition. Wouldn't want to leave it like that.
the choke is not working properly
A 350 Chevy engine can backfire on acceleration due to several factors, including an incorrect air-fuel mixture, typically too lean, which can cause combustion issues. Timing problems, such as incorrect ignition timing or a malfunctioning distributor, may also lead to backfiring. Additionally, issues with the intake or exhaust system, like vacuum leaks or a clogged exhaust, can contribute to this problem. Regular maintenance and proper tuning can help prevent backfiring.
Backfiring in any motor is either badly out of time or a burnt valve.
It's lean. Could be a lot of reasons why. Start with the vacuum lines, then the timing, carb, fuel pump, intake gaskets, etc. Look for anything worn or leaking and fix it.
either the timing is off or you have a plug wire crossed.
