I'm working on one of these and it has thrown the drive belt off. Does anybody know which way the drive pulley should be on. At the moment the pulley is on with the boss section with the grub screw facing the underside of the motor. I'm wondering if I reverse the pulley and have the top of the pulley up close to the underside of the motor this should act as a keeper and prevent the belt from coming off. Any thoughts?
