Random B18 engine anomalies 140-160 1968

I think I've been able to confirm a few things, but unsure of the cause.

First, I can get the car to idle now with the choke all the way in. It's really rough, though, struggles a lot. 12 flats down still on both jets.

Started reading about the lifting pins, and how they raise the piston, but I'm not sure how to see the piston raise, like some tuning instructions reference.

Anyway, I lift the rear carb pin all the way, and absolutely nothing happens to the engine. Roughly idles along with no change. When I lift the pin of the front carb all the way, it dies immediately. Instructions say that means it's too lean. Should I not lift that pin all the way?

Does the lack of any response on the rear carb lifting pin mean I'm not using it at all, or no fuel is flowing to it at all?
