Hi Paul,

My Webers ran best at 3/4 turn out.

If you need to go to 2 turns, your idle jet is lean.

When adjusting mixture strength, doesn't matter which cylinder you start with, or what order you follow from there.

First up, they need to be balanced accurately with a synchrometer.

Then playing with each mixture screw should make that cylinder go rich or lean, the cylinder "goes away", almost like pulling a plug wire.

IDFs can have a starting circuit, cable operated, or come with a blanking plate.

A little disappointing your supplier didn't give you info for your settings.
But that is easy enough for most of it.
Can you look down the venturi and note the number cast into it?
Factory settings for 44 IDF are 36mm venturi, 4.5 aux, 135 main, F11 emulsion tube, 180 air, 50 idle, 50 pump, 50 exhaust (pump inlet valve).
