In later versions of ZS carbs, with needles that are adjustable through the top of the damper, what direction is the needle moving when:
Adjustment screw turned clockwise: Needle moves up or down?
Adjustment screw turned anti-clockwise: Needle moves up or down?
I can physically/manually reposition the needles in my early carbs (C3150) by removing the top cover, pulling out the air-valve/piston, loosening the set screw and then pushing the needle up/in or pulling it down/out.
Obviously more of a PITA operation compared with "tool adjustable" needles and I'd just like to know which direction does what in terms of enriching or leaning.
