"Plugs 2 and 4 have high carbo

"Plugs 2 and 4 have high carbon after prolonged idling. The shop manual talks about the idle adjustments being limited by a modification which allows only about 1/8 of a turn on the adjustment screws. However the manual doesn't talk about which direction leans out or enriches the mixture. If this screw on each carb is an air bleeder then it's CCW for leaner, but if it's a fuel flow control then it's CW. Anybody out there know? Thanks."
