Sounds like the carburetor needs to be looked at, may be flooding out. If you can get it started, try tapping on the carburetor and working the throttle revving the engine up. If there is a piece of dirt in the needle valve, this may work it threw. Otherwise it would have to be rebuilt. Also a bad fuel pump can cause this, fuel pressure would need to be verified.
