Tom,

With it working by pumping the pedal when it's hot, you either still have
air in the system or one of the two cylinders is leaking.  To cure the
former will require more bleeding.  To test the latter, pull back the boots
on both cylinders to see if any brake fluid is getting past the inner seals.

>I replaced my clutch MC and slave.  I verified the pushrods were set per
the book (MC pushrod at 2.95" and slave pushrod at 3.05").  I set the
freeplay at 0.100".  I pushed almost 2 reservoirs of clutch fluid through
the bleeder (no bubbles).  I ended up having to extend the slave pushrod
about a turn and half so the gearbox wouldn't crunch while standstill
shifting through the gears with the motor running.   See some space between
the pressure plate and clutch disk (measured 0.018") and some smaller space
between the clutch and flywheel (couldn't measure).  With the car in gear
and the clutch depressed I can move the car by hand (no clutch drag).

>Here's where it gets weird.   At the start of my test drive, everything is
great.  All gears shift smoothly, clutch engages about half way up the pedal
stroke. Drives like it is supposed to.   After I drive around for about 10 -
15 minutes, the clutch won't fully disengage at full stroke (gears won't
engage without having to pump the pedal).  After limping back home and
pulling into the garage in 2nd gear, I push the clutch in and it sounds like
the clutch is dragging the engine down (again not fully disengaging).

because I haven't had any clutch problems for over 20 years.   All ideas and
suggestions are welcome and desired.
