Diaphram Clutch, What spring?

There IS a light spring on it. There's a spring on the clutch adjuster that pulls the fork back, and that should be more than strong enough to keep the throwout bearing from being in contact with the diaphragm. It is on mine.

Yep, the spring was standard from the factory even with the OC spring; it is called an 'anti-rattle' or 'fork return' spring. (BTW, the OC spring may not actually pull the pedal all the way up, as it's force can be fully released before the pedal is at its full up position.) And even with the pedal all the way up, the pushrod to the fork will still be loose, and the fork prongs and TO bearing are free to move forward. So the anti-rattle/fork return spring is there to pull the fork and TO bearing back, and helps insure that the pedal is fully up too.

The fork return spring is partially shown in the diagram halfway down this page. There should be a slot and small hole beside one end of the slot in the fork; you slip the rounded end of the spring through the slot and hook it into the hole; this was done for easy R&R. There will be a small hole in the bell housing and block area straight forward in which to hook the other end of the spring.
