action entirely "un"sluggish

[studio_guru]

I am experience an issue that has occured ever since I removed the harp to do some internal cleaning and vacuuming.  When I push a key down and release it, it kind of "bounces" back.  It's not enough to make it double strike but it's enough that you can hear the bounce in a recording.  It seems to be more obvious in the lower half of the board.  Any ideas?

There is a song from a band called Heatwave, titled "mindblowing decisions". The introdction is just a Rhodes with three separate notes that can be heard bouncing back as you describe. I guess they didn't mind in 1977.
I think that backchecks are quite a good idea and would probably eliminate most keyboard issues if done correctly.
