the best way to do this is with 2 persons.
one at pedal
and
make sure all parts, move, and no slack, this means all parts move, as one, no delay , no slack , or this is wrong, (just for this 1inch test)
then the 1" rule,
the clutch must fully disengage, with no slack, and the bell lever moves 1inch, or the clutch itself is bad (in the bell what ever bad there)
once this test passes
set play to 1/2" in the pedal (this is center of spec)
