I have a loose belt (new and correct pn#) the drive belt fits loosely on the clutch's so much that the belt can be grapsed and slid forward and back over the clutches with very little friction.
Is there a way to check the engine mount location (too far aft?) and also the sheave of the secondary seems a little wide for this belt (secondary cam slider shoes are almost new)

secondary closed all the way? top of belt should be flush or just above the sheaves when closed.
