Which direction do I turn the MPU?

Could someone please tell me which direction to turm the MPU adjustment screw to lean the fuel mixture on my 1972 350sl.
The adjustment screw faces away from you. I read somewhere that turning the screw clockwise leans the mixture.
Does turning the screw clockwise screw the adjustment screw into the unit or back it out of the MPU?
