I believe there are 2 types of clutch cable fitted to the Mk2, manual adjusting and automatic adjusting.
If you have a manual adjusting type, it may require adjustment.
The only adjustment that I know of is for freeplay at the pedal. With the Mk1's, if I remember correctly, you adjust for around 1" of free play at the pedal. With the Mk2's I think its less than that.....but your Haynes manual should cover all of this.
There is something else that rings a bell about the actual pedal stop getting bent and allowing the pedal to ride up too high on the Mk1's. I'll have a look at my stripped out Mk2 later and see if the same may apply.
