Hmmm. Once I have equal airflow (at idle and off idle) and equal and
correct mixture I set the idle by turning *both* screws by the same amount.
Thereafter any adjustments to either mixture or idle are always done the
same - both by equal amounts - but I find that once they really are set up
correctly they can stay in tune for a couple of years, with the exception of
an occasional increase in idle speed as plugs and points deteriorate.
