What I did was to completely regulate the dampers. Had to bend all the damper
wires out a bit so that I had a rough regulation (very rough) that had the
bottom part of the lever in a more reasonable distance from the string. Then it
was bending the  spoons in rough so they were out of the way for basic pedal
lift adjustment. Evened out the pedal adjustment, adjusted the pedal itself  and
then regulated the spoons.

A bit time consuming, and shoulda been unnecessary, but hey... thats why they
pay us the big bucks... grin.
