[Mgs] MGA clutch

[Barney Gaylord]

If the hose is clogged the clutch will be slow to engage when you let 
the pedal up, but it does not necessarily slip after full engagement.

The clutch pipe and hose are large bore for quick flow to allow fast 
engagement of the clutch.  If you press the pedal full down, then 
lift your foot as fast as possible, the pedal should follow your foot 
as fast as you can lift it.  With only moderate speed of pedal push 
and lift the down force and up force pressure of pedal against your 
foot) should be very similar.  If the force required for rapid push 
is high, and the return pressure with rapid lift is substantially 
lower, that is indication of a clogged hose.  If the pedal goes down 
easy and comes up quick with nearly same force, then the hose is probably okay.

If the clutch slips when you push the throttle on steady cruising or 
going up a hill, then the friction disc is likely worn thin at end of 
life.  Lots of oil on the clutch parts can have the same 
effect.  Either way the engine has to come out for inspection and repair.
