Patrick, I had to think about this one for a moment or two, (maybe even three<G>). I the piano was played a lot "with" the lost motion, there is more than likely a nice little "Pocket" in the butt leather. When you adjusted up the lost motion, now the jack will have a harder time getting out of that "Pocket" to go into let off. You might put some "Slip Spray" on the butt leather at the jack contact point. Just a thought. Best Regards, Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
