Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
The only reason that you would be getting fuel into the crankcase like that is if the float or float valve is sticking and not sealing. I would make certain that the float valve moves freely in the carburetor bore, it sounds like it may be stuck in the closed position now and not allowing for any fuel to enter the bowl of the carburetor which will cause the engine to not run on its own as you are indicating since you have to spray fuel into the carburetor to get it to start. The fuel solenoid if you have one could cause you to not get fuel to run but will not cause the carburetor to overflow like it did and have fuel in the crankcase. If you need additional assistance feel free to ask.
Thank you it has been a pleasure to assist you.
