hey paul,
i did a few tests last night with an LM-1. i set my idle mixture to 14.3, it did move around a little between 14 and 14.3. 2500RPM in neutral, 1st, 2nd, or 3rd all resulted in about 15.2 AFR. same results for 3500 RPM. around 4K it was starting to get richer at 14 AFR and continued to get richer, i think 5k was around 13.5. flooring it at 2500- 5500 produced 13.2 AFR.
in the end, 2k to about 4K was a consistent 15.2, + or - a few tenths, that may have been due to my foot .
then i did a quick test changing idle mixture to 13.3. steady mid range driving was about 14.5. about a consistent 1 point change across the RPM range.
before i changed my mixture to 14.3, it was set to around 13.4, that is about 3% according to a chart. the engine was still dipping down low then coming back up to idle when i let off the gas, this was after i lowered the idle down from just over 1k.
when i set the mixture to 14.3, it seemed like it was very lean. if i richened it from 14.3, the idle would increase a little and seemed like it ran smoother. this "edge" where it idled up was at about 13.7 AFR.
