Those are normally-closed solenoid valves. With no power to them, the internal spring causes them slam shut and are supposed to prevent more fuel from entering the carb bowl.
There must have been something mechanical jamming the valve open? Dunno.

I think that is how they are supposed to work but something must have been messed up on this one.
I took the float bowl apart and the solenoid out and didnt see anything,the battery going bad may have allowed it to get stuck and let the gas seep into the oil.
The mower had been sitting for some time and that may have been what was wrong.It seems to be doing ok,I mowed with it and didnt have any problems.
