Gas leaks out of the muffler when the mower sits for a while. The motor

Thanks

float is stuck or bad

This is what I figured, but in a motorcycle group, someone was told
that if the petcock wasn't closed, gas would go through the carb and
get into the oil when the engine wasn't running. Why wouldn't the
float valve be as good in a motorcycle as in a car or lawnmower?
