[Healeys] Heavy clutch question

[Oudesluys]

This happened to me with a Jensen Healey. I just could not find a cause 
untill I decided to to take the clutch apart again. I noticed that the 
blades of the diaphragm spring in the clutch cover were thicker than in 
the original, hence: /HD clutch or racing clutch/!. Replacing with a 
standard item restored everything to normal.
Also when you enlarge the diameter of the clutch master cilinder the 
force to press down the clutch pedal will be affected by being heavier.
