KZ650 Carb Air Screw Adjustment

The temps dropped here in Massachusetts, and in fiddling with my air screws I've forgotten where they were when my bike ran. It's 50° F out as of this post, anybody in my area or temp range relatively near the coast of anywhere have the air screw setting for a stock KZ650? I understand the ones after 1980 had slightly different air screw settings. I'm trying everything right now but help would be appreciated.

To fine tune the air screws I take it up to 2500 and dial out the miss.
