William,
Try weakening the spring until the note misfires ( too little tension ) =
and then just tweek back stronger. Also place the action back and look =
at the rise of the hammer in the piano. Sometimes a different view helps =
judging the amount or speed of the hammer movement.

  William asked: "Also tried varying the backcheck height, which showed =
no noticeable
  improvement with either higher or lower backchecks.  Also tried =
changing the
  backcheck angle - again no improvement one way or the other, hammers =
simply
  will not check on soft blows."

  William,
  If you've tried all of that, then it has to be something you didn't =
try.<G> Have you checked to see if the keyframe is bedded properly? I've =
known that to mess up checking.
  Best Regards,
