There was clearance between the end of the spring and the jack wall.

I didn't see a bend and it is affecting nearly half the keys.

jump when released from check!

There didn't appear to be too much spring and I did adjust spring tension
and jack height to extremes and back.  I may have overlooked something, but
I am picking up the action Monday to take to my shop and I will repin,
reposition, readjust and maybe regret.

Thanks for the leads,
