Gene ? What type piano is this?This is the reverse situation from what I usually see. SO here are the fixes. reduce the distance the knuckle is from the pin. Meaning insted of where it is, bring it closer to the center pin & or?and the capstans toward the rear of the piano till the blow works with the dip that is present. This sound like a 4.5 or 4.8 action ratio. ?
