My suggestion: take the PTO out (not a hard job, just requires a little
care and patience) and put it on a clean sheet of paper on a clean
desk. Disassemble it, observe its workings (you'll need to remember
details later!), make notes regarding the small parts and just get the
feel for how it works.
Thoroughly clean all the components (I use a "self cleaning" bearing
lube from a bike shop, cleans out all the bad stuff) and dry them off
really carefully. Re-lube (again, bearing lube from a bike shop will
do quite well) and reassemble right there on your desk. Put on the
knob and get the "feel" - see if you now like it. If not, take parts
off and reassemble till you get the "feel" you want. The number of
washers in the rear are critical to the "tightness" of the operation,
and there are other parts that can be moved a bit here and there to
alleviate "lumps" in tuning (the little washers may be dirty or need
some lube, the pins may be stuck in too much to one side and binding).
I've found that by just playing with the PTO once, noting my sense of
the whole mechanism, now I can pretty much rebuilt a PTO to feel the
way I like reliably well, usually with no parts replacement (though I
keep a spare rebuild kit around, buy one from Ten Tec just to have
nearby!)
