<html> Hi Dave,              If the arm is not protruding high enough above the keybed, remove the mounting blocks and remove about 1/8" from the bottom of the blocks.  Re install and regulate the pedal adjustments.

It seems to me that the end of the lever that pushes on the action is not quite long enough to do its job.  It's a brand new piano, and it was working fine before I removed the action, according to the owner.  Any ideas?  Help!!
