[QUOTE="CedarRiverScooter, post: 473439, member: 15465"] Update - I measure things more closely & found shaft more worn than the holes. Got a new shaft on order so that should fix it good enough. But I think RBW is right & that is not the problem. I was checking the throttle linkage & noticed the points plate moving up & down when rotating. So I took it apart & found the threaded reainer ring (for points plate ) was upside down. I think this explains why the throttle movement was not smooth. But wait, there's more! While fixing that, I notice that the points cam was twisted past the key. Maybe that's the problem. Fortunately I have a parts motor that had a useable cam. What I am wondering is what caused the cam to wear so badly? [ATTACH type="full" alt="cam.JPG"]105236._xfImport[/ATTACH] [ATTACH type="full" alt="key.JPG"]105237._xfImport[/ATTACH] [/QUOTE]
