Have you tried a new spark plug?

Drain the carb and let the air filter dry out. Add 3-4 ounces of alcohol to the gas tank and try it again. If you sucked water from the filter into the air jets, you may end up with the carb off the bike to get it out of there.

Try to pay more attention during your English classes, too, if you don't mind.
