Rusty?, Razor?, You need to work on your "circle of jacks" regulation. Repetition tension, jack in line with knuckle, jack in the window. Repeat several times. What is probably happening in your case is the jack is too high in the window.

I'm regulating an action from a Baldwin grand and have run into a rather odd situation with the rep. spring. If I set the hop to a nice positive lift, the hammer shank will fall when I trip the jack with my finger. If I set the spring to support the shank after tripping the jack, the hop has a serious kick. This condition is throughout the action. Any ideas?...
