The mower wouldn't start. When I lifted the engine cover there I ralized there was gas all over the floor. The fuel line was intact. The leak appeard to be comming from the carb and the muffler. When I took of the air box, the carb was very wet with fuel. When I pulled the spark plug, it was saturated. It delivered a spark. I noticed smell of gas when I sat on the mower, so I don't think the fuel problem was from the act of starting the mower.
