a puzzler....at least for me

[pmc033 at earthlink.net]

White keys hitting the keyslip because it's too close, make clicking sound.  Resistance as the keys rub on the way down.

 List,

Action clicks have been costing me  time of late.  I had yet another click today.  The piano is a Kawai K-30 upright.  

On hammer blow, there's a click, as well as some resistance late in the key stroke.  This was happening on many notes in the middle section of the piano.  I thought I'd cured the problem at my last visit when I regulated the backchecks to catch the hammers sooner.  I found more clicking today, though.  I was determined to find the cause rather than to try to treat the symptoms. 

What it isn't: 

jack hanging up or hitting anything it isn't supposed to
loose hammer head or shank
loose catcher or shank
loose anything

Some of you long-time techs should get this one in a hurry.  It was a new one on me, though.
