Re: clutch pedal return spring?
The large spring under the dash is an 'overcenter' spring. When the pedal first starts down, the spring is being stretched slightly. With further pedal movement, the spring passes over the pedal pivot point, and from then on, it contracts and pulls the pedal downward, helping your leg.
When the pedal is not coming all the way up, it usually means that the clutch is not raising the pedal above the 'overcenter' point. Lengthening the linkage should cure that problem.
If you do change out the spring, the FSM has a 20-step procedure for removing it and a 24-step procedure for reinstalling it, with several more instructions for CJs with power brakes. If you need it I'll scan it for you.
