I have a 2001 LT 80. it cranks but then loads the cylinder up with gasoline and can't turn over. I pulled the spark plug and a lot of gas shot out of plug hole. I cleaned out the carb jets and float bowl but it still does the same thing. is it maybe leaking past the needle valve and flooding the chamber? After I cranked it over to get the gas out of the cylinder I dried the plug and it started with the gas shut off, then stalled. When I turned the gas on it cranked but no start. Then it turned over very hard . No gas in cylinder this time. Ideas? Jim
