For me, this was the adjustment nut on the clutch linkage. It should show about 1" of thread when adjusted properly. I would tighten that linkage first.
You can tighten it almost all the way to make sure it works, then back it off to where you like the feel of the clutch. My linkage was missing the wave washer and it loosened up. I suppose you could also double nut the thread to keep it set.
