If a two cycle would normally fill the crankcase even if the fuel was able to make into the engine. Now the 4 cycle version are more regular 4 cycle engine we normally and it is a slim chance it could flood the cylinder. Either way the check valves and needle valve should fuel from leaking into the engine. I do know the metering diaphragm when stiffen from age will allow the fuel to pass the needle valve at less than normal pressurize tank pressures.
The truest measure of society is the how it treats its elderly, its pets, and its prisoners.
