I’m trying to adjust my clutch too. I’ve replaced the slave cylinder & flexible pipe, bled the system, topped up the master, adjusted the big nuts to 1/8” gap, adjusted the stop to 20 thou. Now before I put the spring back on the clutch will disengage right at the bottom of the pedal travel but once the spring (& it’s the old one with limited tension!) on the clutch doesn’t disengage. Basically the same as it was with the original slave. Perhaps it’s time to replace the master. I presume it can’t be the clutch as surely it would be more inclined to slip if it was worn. I suppose it could be the release bearing but there’s no noise. Not sure where to go next!
Basically the clutch slave cylinder can only push 20 mm; we have to set where this amount of movement starts and ends.
Starts:
First, the small 1/4"UNF screw is set to 20 thou (more or less isn't important - but must have some gap so the throw-out bearing isn't running in contact with the diaphragm).
Ends:
Screw the lock nut and stop-nut away from the clutch cover so they are out of the way.
Press the clutch pedal several times to allow it to adjust its range of travel. The pushrod should move about 20mm in and out if OK.
While the clutch pedal is down, screw the stopnut up to the clutch cover, release the pedal and turn stopnut 1 flat more.
Fit locknut.
It seems that when you've fitted the return spring it has added extra travel that the slave pushrod can't make up so doesn't quite disengage. Try making small adjustments of the 1/4" screw outwards - less clearance.
Then read 'simonw' comments.
