If the float is not stuck the needle and seat are not sealing, it could be a worn needle/seat or dirt jamming the needle. With fuel running out of the overflow, your engine should be flooding if anything (and this will also prevent it from starting) check to see if the spark plug is very wet after you have tried to start it several times.
