First, I would try to determine if it is a fuel problem or something else.
What is the exhaust doing? Black smoke? Too rich.
Strong smell of unburned gas? No ignition.
Little smell? Too lean.
If it will only run at full throttle, you should be able to look into the carb and see fuel being drawn up out of the main jet. If you see fuel going into the intake and the engine is still not responding, it's probably something else.
If no fuel is visible, give it a shot of gas with an oil squirt can, it should instantly rev up. If it does rev, it's not getting fuel through the carb. If it dies, it's getting fuel, maybe too much.
If it turns out not to be fuel, might look at the ignition system. Disconnect the kill wire, look for damaged wiring, especially around the flywheel, around any moving areas like the handle bars, suspension areas, etc. You should be able to pull the plug wire slightly away from the plug and see or hear the spark, determine if it's a consistent spark or intermittent coinciding with the "pop-pop" running.
Other possibilities could be broken valve spring, sticking valve, or tight valve adjustment.
