The cams are worn, too. I was young and new to them then and didn't know much. I noticed the pulley would wobble up and down so I pulled it thinking it was the right side bearing. Turned out the left side bearing was shot. It caused the cam gear to work up and down which caused damage to the crank and governor gears and governor bearing and shaft. Fan gears were shot, too, but I put new ones in. Gonna take about .030 to clean them up. I can work out a way to grind them, just want to be sure I don't lose the hardness. Do you have any parts left?
