Clutch cable adjustment

[Dead Eye]

What does the Haynes say?

The nut is used to tighten against the cover to prevent the screw from turning, the actual screw does all the adjustment. I've found that on mine that when tightening the nut the screw doesn't move. Even then, it may only move a slight amount when the nut begins to tighten against the cover and isn't anything that can't be corrected at the lever end, though I've never had this problem
