The gasoline line from the gas tank to the carburetor in my riding
mower has no shutoff valve. It is a carbureted engine.

This week I filled the tank in the riding mower. Later the same day, I
noticed a gasoline smell in the garage, and traced it down to the
mower. It was dripping gasoline out the exhaust! The engine hadn't
been run in more than a week. The gasoline level in the tank had
dropped about a quart!!

The only way I can figure that gasoline could get from the tank to the
exhaust is through the float valve in the carb. Do most inexpensive
carbureted riding mowers nowadays have a float valve in the carb and no
shutoff valve in the gas line??
