The engine isn't overheating. The pump was simply not providing the right amount of fuel at the right time, in regards to throttle setting.

Today was better. The T-loop mod did not work; apparently, one must have a check valve in there somewhere, and I was fresh out.

So I started over, and got a decent mix this time. I believe I had the pump pressure too low. The low-end is still a tad too lean, and I had to stop tweaking due to rain. But I got three good flights in, really working the throttle, with no major hiccups. It was again too windy to do any trimming, anyway. I'm aware of the trim procedures; we've already done Tobe's plane.

Our crosswind runway is too short for these big planes, so I was landing in a 20 knot quartering crosswind. Man... this plane really locks in on approach with a bit of speed. I believe it will be a superb IMAC flyer. Mine has a half-degree of wash-in at the left wing tip. The only way to fix that is to strip the covering and move wood, which is more effort than I'm willing to expend just yet. So I'll live with it for now.

As for mixing, I have a 9Z, so that won't be a problem. I hear you regarding stringing two or three manuevers together; we were discussing this today, and are seriously considering getting sims just to program the stick movements into the old cranial hard drive...
