While preparing my Snow Devil snow thrower for storage, I ran the engine for a few minutes and turned off the fuel supply. Since the fuel already had stabilizer in it, I topped off the tank and put it back in the garage until I could get my mowers out of storage to make room for the snow thrower. When I came back for the snow thrower, there was a puddle of gas below the tank. It has been dripping now for almost 24 hours. The machine is about 18 months old and I have never used the fuel shut off before. I am not familiar with LCT snow engines and don't even see how to get to the tank or the back side of the fuel shut off. Any help would be appreciated.
