There can be several different causes. Basically, it can be the ignition system or the carburetor. Too much oxygen in proportion to gasoline will cause backfiring. Also air leaks in the hose that connects the air intake to the carburetor. A faulty CID can possibly cause backfiring, however this is not as likely as the cause I mentioned first. There are other possibilities, but I would suggest a geneal tune up and inspection of the spark plug.
Make sure the accelerating cable in the engine compartment is not too tight.
