Jumpy Tuning PIns

Regarding the jumpy tuning pins in the piano I'm restringing, I meant to say 
that they are so jumpy that I believe the piano will be very difficult to 
tune.  I read the naptha suggestion in Reblitz.  Almost half of the tuning 
pin holes have the "black" in them but this wasn't obvious before the old 
pins were removed, or I may have backed out on the job then.  When I tried 
the 3/0 instead of 4/0 there is less jumping and creaking, but the torque on 
those is only 80 or a little more.  Isn't that too loose to start with? Also, 
when I tried a new pin (4/0) in a hole with no "black" in it, it was jumpy 
too and did seem too tight (torque 160).  I tried tuning pin driving fluid 
(APSCO) in a couple of the holes.  At first it seemed to do the job and 
eliminate the jumping, but a couple of hours later they were almost as jumpy 
as the others. Any ideas would be appreciated!
