Usually the full throttle A/F is set close, then timing and then wide-open full throttle A/F is fine tuned. Next is the idle circuit and initial timing. After that advance curve and transition circuit and then finally the vacuum advance.


Since the above strategy usually requires a dyno session and or a trip to the track. That's usually not done with a street engine, I'd start with the idle and end with the vacuum advance. Just keeping in mind timing will affect the A/F.


A vacuum gauge visible from the cabin and patience will pay dividends when tuning the timing curve.
