Only one day left, any more guesses?

Never tried setting idle mixture using the fast a/f display (and vacuum gauge at the same time) until earlier tonight, and that was different.

The RPM is higher, the vacuum is higher, and the idle feels stronger at 17 or 18:1 than at 14:1 for some reason? When I set it by ear or vacuum it ends up at 17 or 18:1 every time.

I put it in the 14s at operating temp thinking maybe it will help it run cooler at low speeds Don't really like the fact it makes the quality worse, but don't understand what's up with it. Need more time playing with it I guess.

Nothing left to do but swap a couple parts around tomorrow, fuel up and take a spin.
