Greetings from Germany! I have restored a JD 65 (A650H 097657M) and everything is running correctly EXCEPT the deck. The spindle, pulley and idler are all new. After mowing for a few minutes the belt will twist and eventually pop off. The pulley on the engine shaft is also straight. Any ideas out there? I am also unsure of the proper setting for the belt guide around the engine shaft pulley. Thanks for any help offered! :dunno:
