I don't know of anybody that only monitors one cylinder. Mine measures three, Joe Horton has two, with each measuring three, all automobiles measure all cylinders at once downstream. >>2. Would you want to adjust the mixture on takeoff by this gauge to >>maximize HP? You want to take off with the mixture a tad rich to minimize the possibility of detonation, and for max power. It won't take you long to figure out where the mixture meter needs to be set to get that. On my AFR gauge that's with the second LED from the top lit, and the top one no lit. >>3. Once leaned to 14.7 afr is there any reason other than an altitude >>changes to touch it? With my Ellison (and I'm guessing most other carbs) a change of throttle setting will also change the mixture. I adjust my mixture quite often while flying, especially after initial climbout, as I climb through 5000' feet or so, and then when I'm at final cruise altitude and have backed off to cruise rpm (about 3050, most of the time). And not just to 14.7:1, but far below that, with only the lowest LED blinking occasionally. There's more on that at http://www.n56ml.com/corvair/o2meter/ .
