Lost Motion and Touchweight

Hello all: I got a call today from a customer whose Knabe console I serviced
at the end of July. She complained that something I did has made the piano
have a very heavy touch, not only to her but to her husband, and she wants
it put back to its former condition. I looked up my record on the piano and
saw that aside from tuning it I adjusted the lost motion.  I have never had
anyone complain about the piano having a heavy touch after having the lost
motion adjusted. My experience has been that the piano plays better, and
previous tuners may have been ignoring the need for the lost motion to be
taken up.  She says that she has had it maintained by well respected
technicians where ever she has lived, the last one being the technician for
a Steinway dealer. She has moved out of his service area, which is why she
called me.  I am at loss to figure out how taking up the lost motion could
make a piano have an uncomfortable heavy touch.  My guess is that she had
grown accustomed to playing an out of adjustment action, and that a properly
adjusted action with a firm touch feels "heavy" to her.  I have an
appointment tomorrow morning to check the piano over and do what is
appropriate to satisfy her, but I'm scratching my head as to how to put the
piano back out of adjustment in order to satisfy her. Has anyone run into a
similiar situation?  My notes do not mention any sluggishness or tightness
in the flanges, and she says she noticed this change in the touch
immediately.
Thanks, Patrick Poulson, RPT
