Before you move the mount on the trans, try to get a bit more travel out of the piston in the master cylinder. The clutch pedal should be attached to a threaded rod going into the M/C. I had the same problem and screwed around with the slave stroke, then tried to get a bit more stroke out of the M/C. Problem solved, the clutch works so smoothly, don't know why I ever had a cable in it before.
