Take the fuel line off the carburetor inlet and put it into a container like a motor oil bottle. Then loosen the bolts that hold the fuel pump to the engine a couple of turns, and work the pump housing up and down by hand until gas flows out of the line at the carb. It's easier on the starter than grinding it over for long enough to get the fuel to flow. If it doesn't flow gas in 15 or 20 cycles of the pump, you've got an air leak on the input side or a bad pump.
