Try tapping LIGHTLY on the front float bowl. Sounds like a stuck float.

Dirt may have lodged in the needle and seat.  If Cooter's idea doesn't work, then disconnect the fuel line from the carb, and plug the end of the fuel line.  After the excess gas evaporates from the engine, it should start.  Run the engine until it runs out of gas, then hook up the gas line.  Restart the engine, and the rush of gas through the needle and seat will usually wash out any dirt.  If that doesn't solve the problem, then you'll have to remove the float bowl and inspect the float for damage, clean off the needle and seat, and check the float setting.   Good luck!
