this just started, when im moving everything works perfect but soon as i let off the gas i get a bad clicking sound. if i give it alittle gas the the clicking stops. it only does it under load. any ideas would be very helpfull. if i idle the carb way up it wont click but its agervating to have idle so high. sounds like it could even be coming from the clutch. i rode with the cover off but i cant tell. the rear pully has alittle play in it if i wiggle it up and down. thanks

please any ideas at all would be great. i dont have the money to put in shop. my daughter really wants to ride. thanks
