"MY" procedure is to set the high speed adjustment so the belt rides the same on the motor pulley at fast as it rides on the idler pulley at slow. I feel that evens out any things that are 'weird'. The idler pulley limits the range of adjustment available(the motor pulley merely responds to that so as to maintain belt tension). I think the belt is slightly 'narrow' since it is an off the shelf automotive belt.
As I mentioned the headstock is not 'standard' since it has poly-v stuff and a non-standard belt as well as an altered motor mount. FWIW the motor is also reversible. The poly-v belt tension(eccentric setting) is set near 7 oclock(new belt). That makes the motor offset less that if the eccentric was adjusted for increased tension(towards 9 oclock).
I will review this thread so as to maybe solve the mystery. Something is being overlooked. Not tonight!
