I thought the tabs are supposed to stop the sleeve from sliding down the inlet, but not capture it, so that when the motor is dropped, the sleeve and bellows are still attached to the frame.....?

UTC quote If you rotate the locking ring clip so that one of the slits of the sleeve are open to the ring ends it becomes real easy to swing the engine down with bellows and sleeve stating in frame. And you just leave it in that position for good. ⚠️ Last edited by scootermarc69 on UTC; edited 1 time
