Mine does the same thing when flying, but it's instantly apparent with the mixture meter (which both Dan and Joe also have now). And it's normal for an engine with no acceleration circuit to go lean when the throttle is advanced, but it should catch up shortly and run correctly, but that's not the case with my Ellison installation. But I don't really think that's it as Joe now knows exactly what's happening with the mixture. At the same time, I do think it's mixture related somehow. Mine is adjusted such that if I take off at full throttle, the mixture's perfect, but if I back off a little, it goes full rich and stays there until I fix it. And there's no way to adjust mixture at WOT as opposed to part throttle, as far as I can tell. The Ellison folks seemed to be bumfuzzled at this phenomenon, but then I'm running ram air, so shouldn't complain about funny behavior, and I've learned to work around it, even though it's clear it has nothing to do with ram air.
