it is your carburetor the fuel float is set to high and probably leaks. If it older than 10yrs old and has never been rebuilt . do that if you want to save yourself a bunch of time and little more money make the investment of a Brand New not rebuilt. if you get the carb manufactor specs matched to your motor , Out of the box, it will be very close to being on the money .
Turn the ignition switch to run, without starting it. You should hear the electric fuel pump, in the gas tank, run for about 3 to 4 seconds, until it builds to proper pressure. If it is not humming along it needs replaced. murf427
Most likely is the clutch inhibit switch, the switch is on the rod that goes from the clutch pedal to the the clutch master cylinder.Could be a bad ignition switch but that is rare.The clutch switch is designed to keep the vehicle from cranking without the clutch engaged.Make sure the floor mat is not wadded up under the pedal.
sounds like you need to rebuild your carb. I just had mine done for my jeep the hardest part was finding someone to do it. ps mine only cost 50 bucks so dont get ripped off. good luck and hope this helps.
with little infomation i would say that you need to replace the fuel pump or you shoul start with the fuel filter then if that doesnt help try the fuel pump replacement . see when you push it motor is turning faster than starter motor meaning need less fuel to start it so when you push it motor is winding faster than with starter motor good luck with this project
