head filling up with gas?

Chances are there is fuel leaking past the float needle valve. When the engine is running, it uses the fuel faster that the leak replenishes it, but when the engine is stopped, float chamber over-fills, and fuel comes up through the carb jet and runs into the engine.

Solution - remove float bowl and float, clean/replace needle and/or seat, and re-assemble.

I think you need to strip and clean the carburettor - the fuel level is too high, maybe because the float needle valve isn't sealing properly, causing the engine to flood. It also helps to turn the fuel off at the tap every time you stop the engine.
