Mike, I'm sometimes surprised that more folks don't recognize that using a vacuum gauge is the most accurate way to set idle mixtures - maybe they just haven't been exposed to enough of the period service literature. Absolutely correct - maximum vacuum consistent with the leanest mixture!! An engine in good condition and good tune should give about 18" (at idle, obviously).
