Example; is the factory setting a certain number of turns off bottomed out, or does your method apply no matter the current position of the idle-speed knob

No base-setting for idle. Just whatever position is needed for proper idle-speed of 1300 +/- 100rpms. Follow JKV's procedure:

1. To do that, warm the engine fully and let it idle.
2. Adjust the [mixture] screws one at a time to get the highest idle speed. I typically go about 1/8-turn richer after reaching highest speed, which helps smooth the transition off-idle. For now, just get the highest speed.
3. Then adjust the idle speed to 1300 +/-.

So order is:
- mixture-screws for highest idle-speed + 1/8 turn
- idle-speed set to 1300rpms
- leave both those alone permanently and use choke for cold-starts. Its range is greater than all others.
