Paul, It is probably something simple as already mentioned. Here's another idea: check to make sure the edge of the whippen felt is not rubbing the rail slightly--or possibly something like a splinter in the mortise around the key bushing (may need to remove key again off and look with a magnifying glass?) Don't give up you will figure it out!

>Front key pin catching on back or front end of mortise?
That sounds very logical. Definitely worth checking. Back end, if it
got worse from a deeper keydip, would be my guess.

Some bit of something on the whippen rail under the whippen? Traveling
paper, e.g.?

Thats the thing, David! Nothing on the neighborhood is affecting it!
Perplexing! It checks with normal let-off and drop, but then won't fall back
into place. Springs are not real strong, but firm.
Is the key also hanging down when the hammer won't fall back?
Does the tail have good clearance with the back check on the way back up,
when you press down on the hammer while working the key? When you do this,
does the jack cheat?
Have you tried adjusting the lever height, and winking the jack?
Is the jack burying in the cushion when the key bottoms? Possibly the
longer
travel of the sharp (from starting higher) could do that. Have you checked
visually that the jack isn't hanging on the front of the knuckle when the
hammer hangs? If the jack is burying in the cushion you could try pulling
off a little of the cushion and see if that fixes it.
Have you tried shortening the key dip a little bit?
Susan

Hi Paul,
Check the sustenuto tab with respect to the sustenuto
bar to make sure you have clearance. Operate the sustenuto pedal a few
times to see if the damper head blinks.
Make sure you clean all rep spring grub slots, and polish spring tips for a
big improvement in touch. This vintage used tallow for lubrication and has
long since gone hard,
Have fun.
Roger
