Hi again guys. My 1974 tr6 suffers from a sticky clutch. Not all of the time, but quite often it seems the clutch does not react when I am in 1st gear and raise the clutch pedal. It seems to stick for a second and then reacts. Obviously it is hard to drive that way. What do you think? The cylinders or the clutch itself preasure plate disk bearing? The clutch is very heavy to operate. Thanks for your help Steven
