Okay, guys, have no idea what happened. Cutting fine, engine running good. Got finished & headed for the barn when it started to stumble and I shut it off. Cranked & cranked, wouldn't hit a lick. The next day, tried it again & the starter just clicked. Jumped it, no good. Finally I was leaning down watching the starter & it started to turn, then a whoosh & gas was everywhere! Out the carb, out the dipstick, everywhere! The crankcase is flooded with gas. Float on the carb is not fuel logged. What gives?
