Guy,
I am no clutch expert but physics would tell me that if you replaced the slave
cyl. with one of larger interior volume, you would also have to replace the
master cyl. or it will not put out enough fluid to move the new, larger slave
piston enough to disengage the clutch disk fully. Perhaps your PO replaced
both cylinders at one time. See if the master cyl. is of orginal spec. (i.e.
is it the same as originally fitted on your car) or if it matches the years
that the 7/8" slave cyl. was used.

<< Oh -- one thing that may be relevant is that when I dismantled it it had a
7/8" diameter slave cylinder. Couldn't get replacement seals for that and
was told it was the wrong size for the car and year anyway, so I replaced it
with a 1" diameter one. Would that make sufficient difference? Calculater
gives 0.601 sq ins for X-sectional area of small one and 0.785 sq ins for
larger size. Anyone know what volume of fluid is shifted on a full stroke of
the master cylinder?
