your float is stuck.. remove both shrouds and loosen your clamps on your carb. spin the carb to where you can remove the screws from the float bowl. make sure you have the fuel shut off and remove the bowl and see if the float is damaged or if its nasty on the inside. make sure the little pin doesn't fall out where the float hinges and the needle and seat should ride against part of the float through the range of movement of the float. with the float all the way down it probably wont touch. clean the best you can and put back together and see if its fixed.. if not pull the carb off and take it apart and clean..
