MFG Rudder pedals, physically don't recenter, damper mod applied, best settings and where to set?

Just a slight update, I may have goofed or not, unsure, but I thought that the front bolt of the damper was a bit loose, so I tried snugging it, I thought not that far and it has snapped, the plastic piece.

Now i have to hope i can get that piece replaced. However, in doing so I’ve come to realize now they snap back just fine, I guess even a 6 out of 24 on the damper was too much to auto recenter.
