Sometimes the action rides up on the una chorda lever. This or any of the bolt theories produce a noticably shortened blow distance. . . I had a jammed action I couldn't solve once and used screw drivers gently worked inbetween the key bed and key frame, and a good flashlight to scan the terrirory in the crevice. A little wiggling and sighting should narrow it down to one area, then the various bolt or pedal theories can take over. Audrey Karabinus, Seattle
