Try cranking with the coil wire disconnected.
If it still backfires, or more so a compression blow back through the carb, there is a valve problem. An exhaust valve not opening will cause that, and still have good compression.
While the coil is disconnected, hold your hand tightly over the carb intake horn and have an assistant give it a crank. Should get strong vacuum and hand wet with gas.
Vacuum and no gas, fuel delivery problem.
Weak, pulsating, no vacuum, valve problems.
Take a sample from the carb drain bowl. Should get a constant flow of fuel with the gas valve open, not a drip or stop flowing. Look at the sample, should be clean gas, no water or trash. Whatever is in the fuel is in the carb. Usually the bowl can be eased off, cleaned out and reassembled without parts. Pay particular attention to the main jet, clean it with a stiff wire.
