Ok, I'm here!
Here is the Reader's Digest version and the general operation.
The difference between in/out-lean/rich is entirely dependent upon whether the pilot adjustment is in the front (engine side) or the back (air cleaner side) of the carbs.
In the front (like ours are) the pilots turn in to lean, out to richen. They are adjusting the GAS flow for the pilot circuits.
In the back (closer to the air filters), in is richer, out is leaner. This adjusts the AIR flow for the pilot circuits.
Edited cause I got it backwards too, oops....
