Question about 1974 Yamaha RD 250
Sounds you have a problem with the carb float and needle assembly (i.e. the float and needle are not stopping the flow of fuel into the carb even when it is full as they should).
Backfires are a symptom of too much fuel in the combustion chamber typically. Try turning your shut off valve to "off" and let it sit for a day - then try to start it with the valve still off. Ideally it will start and run for a bit - until it uses the fuel available in the carb. If not - provide more detail.
