Sticky clutch pedal resolved. It seems when I went to convert from the automatic BW35 to a Ford T9 5 speed one of the mods was not done correctly due to lack of specs. On the T9 the input shaft sleeve has to be cut down on a lathe in both length ( to illiminate hitting the back of the clutch disc) and diameter (for the Volvo stock throw out bearing to fit over it). The cut on the input shaft sleeve diameter was so close in tolerance that when both the trans and the bearing warmed up they expanded to the point of massive friction which resulted in the pedal feeling 'sticky'. One problem solved 2 more to go.

    Need to remember the difference between "tolerance" and "clearance".
    Problem here is too great a tolerance which resulted in not enough clearance.
    Tolerance is how much variation in size you can stand from what is actually called for.
    Clearance is the difference between the inside size of the outside member and the outside size of the inside member. In this case the tolerance allowed the inside member to be too big.
