Going over a newly-acquired old engine, it turns over freely, but the exhaust valves don't even come close to fully closing. I mean they need a good 1/8" more of travel to close.
Anyone have any thoughts on how both exhaust valves could be so far away from closing? They do go up and down. Intake valves seem okay.
All I could think of was crud on the shafts hanging then up, so I polished one shaft best I could wrapping long thin strips of Scotch-Brite around it and using back and forth motion, and using other methods, but no difference.
