CIS Mixture screw question

Hello everybody, I have tried this question on the 911 Technical forum thinking they might have more CIS traffic? They sent me back here.

So it's a stock 76 ROW 930. It has run rich since I have owned it.

I am getting to know my way round the whole CIS thing. I suspect my mixture screw has been tightened up all the way? and damaged?

In unwinding it it seems to make no difference to the mixture, and it has no detectable click that I have read about. Too worried to unwind it all the way at this stage.

What should I expect from this screw? I am just asking for any pointers before I pull it apart.

Secondly, in the center of the right hand half of this picture there is a screw with a white paint mark on it. Next to the regulator. Is this an adjustment screw? It is locked down so hard I feel I will damage it if I try any more to crack it off.
