TSX662 carb questions

I tuned up a friends 901 Ford with a Marvel-Schebler TSX662 carb. Couldn"t find a drawing but I assume that the idle fuel adjustment needle is the one on the top of the carb. Right? Tractor idles good with it opened about 3/4 turn. Does turning this needle in (clockwise) richen the fuel mixture?

The power needle would then be the one on the bottom of the carb which I set at 1 1/4 turns.
I assume that turning this needle in leans the mixture so I thought it best to set it on the rich side of the initial setting of 1 to 1 1/4.
Don"t think this machine ever operates at the governor under load so tweeking it probably won"t happen.
 
The upper needle on a M-S TSX carb is an air control needle and so tuning it in enriches the idle mixture.
The power jet needle is the big knob one on the fuel bowl and turning it in leans the mixture
