Sounds like the rod for the soft pedal is not seated properly. That could cause lost motion.

  Tom, 

  thanks for the advice about transporting.  

  As far as the jacks go, they click when the key is depressed. As best as i remember, they click almost at the moment the jack toe bumps in the letoff button.   
  One other thing that i forgot to mention, and this may be significant:

  I had somewhat of a difficult time fitting the action into its supports properly. Everytime i thought i had it in, several of the keys wouldn't go down at all.  But finally when i thought it was locked into place, which is when i began checking notes and hearing clicks.  The other problem now, however, is that there's suddenly a whole lot of lost motion, across the length of the action.  Almost every note has 1/32 or so of a gap between the butt and jack.  So, either i didn't notice this before (this is a friend's never-used piano, by the way), or i didn't quite return the action properly.  Could this have affected the let-off rail forks? 

  Scott
