After replacing the compensator and bevel box, I'm down to one niggling problem; a loose gear shift knob. There doesn't seem to be a set screw, it doesn't screw tight or untighten. Has anyone figured out how to remove or tighten the knob? By the way, now that the above mentioned problems have been fixed, my Morgan is as much fun as I had hoped. No problems since. I hope that's not a jinx. Larry S.
