On after touch; I tried raising the glide bolts to see if that affected it, but no. Thanks, I'll post later today.

It is like new, very slight knuckle/hammer wear, but really good shape. I have regulated it and everything seems great except that the let-off bump feel seems excessive and I can't figure out why, on this C3. I have lubed everything, knuckles with Teflon, McLube to all key pins, whippen/jack tops, etc, but when the jack lets off, you really feel it. Also, when playing pianissimo, at the point of let-off, there is a definite wall that you hit and it actually prevents some notes from releasing. I am wondering what aspects of regulation affect this. Or is there something else I am missing? Let-off is about 1/8" to 1/16" graduated, drop a little more than that, checking is close; rep springs are not too strong. Knuckle and jack top shape seem normal. Thanks.
