Doing Great. Sounds like you have the basic idle Fuel/ Air right where you want it. Is your meter a Lamda meter (fuel/air) or a Air/Fuel meter.?
You reported 14.7 to 1. Assume Air/fuel.
You could have slightly more height vs width on the Transfer Slot window and be able to back off the Secondary Screw to 5/8 or 3/4 turn from zero. Then you might have a SLIGHT tension on the Primary Screw (There should be some light tension on the Primary Screw spring to hold the Primary Screw in place (keep it from moving).
Sounds like you are real close on the idle mixture and ready for the Transfer Slot/ Transition portion of the off idle curve.
