[GreenKeys] Questions about the M28 Stunt Box & Code Bars

[John Doe]

Hello all,

Restoring my M28, I noticed that the SUPPRESSION code bar is permanently
hooked in the marking state with its actuator link disabled and the ZERO
code bar doesn't have a detent - so is sprung to the marking state but is
otherwise free to move. I can see rub marks on the SUPPRESSION actuator
links so I know it was operating at some point in the past. I'd like to
figure out why it was disabled to restore functionality. Photos attached.

The manuals and stunt box brochure explain how they work, but not many
practical examples. I'd like to know more about the SUPP. and ZERO code
bars before I go on the hunt for shift forks, pawls, function bars, etc.

Any help appreciated.

Thanks,

Nicholas Gromak
