Clutch issue
Is the current one out of adjustment threads but worked previously?
Longer will allow more adjust but will also decrease clearance between the release bearing and fingers. You don't want the bearing riding the fingers with the pedal up. Also if you adjust too much you can bottom the back sides of the fingers into the disc hub which could damage them.
The 0.060" would be a starting point.
It "could".
