Does anyone out there know how to verify the adjustment on the oil pump? I was looking the engine over today for an over heating issue and noticed the bottom jamnut hanging around the oil pump arm.Thinking this might be an issue I would appreciate a method to adjust for a correct oil flow. thanks

Thanks for the reply. I wish it would have been that easy. No marks on the pump or the lever. I adjusted the cable so the lever was horizontal at full throttle but really that was a guess based on a maint.book for a 88-89 but doesn't mention the 500 eng . I dunno

To verify that it is pulling to full open, make a hook from some stiff wire and pull it up as far as it will go. Then pull the throttle and see if there is any slack in the cable.
If there is, take up any excess with the adjuster.
