You should measure the rearward movement of the slave cylinder's pushrod to
determine if the hydraulics are providing all the travel you need.
Movement should be approximately 5/8 of an inch.
When you changed the clutch, Peter, did you also change the pilot bushing?
A bad pilot bushing "dragging" on the end of the input shaft can transmit
enough torque regardless of clutch engagement/disengagement to cause this
problem, and I would think this might be subject to operating temperature,
too.
