[Healeys] clutch master cylinder problem

Hi Steve,

Did you replace the rubber hose at the clutch?  That hose can soften and 
close off inside where you can't see any problem but it will act as a one 
way valve.  Apparently that is a common problem and I have seen it written 
about many times on this list and others.
