Likely a stuck float is alowing raw gas to dump in the motor, Drain the
oil twice after starting it a minute to get the gas out, dont run it if
the oil level is up, that would mean its full of gas, it is possible to
ruin a motor running it with to much gas in the oil. The carb should be
probably rebuilt , if you have no gas shut off store the gas tank empty
for now or it could flood again.
