Thank you both. A lot of good information. I still have three questions.
1. What keeps the adjustment nut from turning once you get it where you want it.
2. What is the rear nut for? Is there supposed to be a nut there? My thought of it being a lock nut is obviously wrong. You couldn't maintain the 5/32 gap between the fulcrum and the fork if it was up against the backside of the fork.
3. What does the spring do? Does it have something to do with the position of the throwout bearing?
Thanks again,
Mark
