first off check your oil for any water, and not just the engine, you need to check diffs, air box and engine. then loosen the drain screw on the bottom of the carb and drain the bowl with the gas turned off. the turn the gas on and flush the carb for about 10 seconds. tighten screw the check spark plug connecter for water or moisture. replace plug if yuo have one and try it again it should be better. also check your hose on your gas cap to make sure is is clear and clean, when i go deep my steering column fills with water and i have to pull my tank vent out so the carb will get gas.
