I had a gas leak from the overflow valve under the carb. I took the carb apart and cleaned it out really good and all was well for a couple of weeks. I came home today and gas was all in my garage floor(should have turned gas OFF....ooopps) But the gas wasn't coming from the overflow valve. When I took my seat off and opened the air box it was full of gas. I mean full to the brim!! My air filter is ruined but I dont know why that would have filled with gas. It was about a gallon of gas. Thank God thats all I had in the tank or there would have been more. Has anyone seen this before??
