hi i picked up a superwift mower with a yamaha blue thunder 2 stroke on it.i cleaned the carby out etc,and it started up ok,it dies off and picks up again idling,but there is a lot of wear in the throttle shaft.the disc has been damaged and is not worth fixing.its the first time i have seen a yammy on one,my other two are briggs.it seem to work good and was thinking of keeping it,can anyone please tell me a bit about the motor.i guess you can get bits ok for this model
thanks micka
