The stock Facet (Marvel Scheibler) MA-3SPA carb is set up to enrichen the mixture at full throttle to augment cooling and, as Mark said, to help prevent detonation. The EGTs on my O-200 also drop at full throttle. Since I fly high altitude all the time (including take off), I always lean for best performance. When I reduce from full throttle, the engine will run a little bit rough until I enrichen the mixture a bit. Jeff Scott N1213W - Los Alamos, NM
