Agreed!
When I bought my NC at 17,000 miles and six years old the “brake fluid” had been done on the service intervals. The clutch fluid shares the brake reservoir, so should be bled at the same time!
BUT the clutch was on the floor, (a buying haggle point) and my first thought was to bleed it. What came out was pitch black and sticky. Eventually when it ran clear, obviously never bled before with loads of black sludge, the clutch was a lot better.
A few years later I finally adjusted the master cylinder bite point with the aid of a bath stool to support my hips beside the car.
It took two goes a couple of months apart before I was happy. Original post updated with this in mind and a picture.
Now at thirteen years old it is simply excellent, and more recent scheduled services did bleed the clutch slave too.
