Below is my summary from the manual I have:
Bring to operating temp
- Connect Tach
- Connect Vacuum Gauge
- Throttle adjusting screw (idle speed adjustments) to lowest possible where engine runs
- Idle mixture in/out to obtain highest steady vacuum at idle speed
- Throttle adjusting screw (idle speed adjustments) to highest vacuum reading
- Set engine idle speed (which screw?)
