Seagull ST19 (nearly Venus-75) central sec engagement regulation

I put here the pic of the ST-19 for your commodity:

Thank you!

Not exactly sure what I can do to help on this one. 7750's are my favorite way to increase my blood pressure. ST-19 is something I have yet to put a screwdriver to.

Here is a parts breakdown that I think may help,
