Interesting note on Rare Bear - for those of you who were there, you'll remember that he called Mayday during the cooldown laps with a stuck throttle. John Penney could not reduce power below 35" and 2400 rpm, and only had about 8 minutes of fuel left onboard at that power setting. September Fury was still sitting smack in the middle of 14-32 with a blown engine from Mike's mayday on the next-to-last lap, and the other unlimiteds were recovering on 26. There was very fast rush job to get Sept. Fury off the runway, John gained a few thousand in altitude, killed the mags and did a gorgeous deadstick on 32. The final cause turned out to be some body filler that came off the very-recently rebuilt cowling and was ingested into the engine air intake on the wing root, some of it got caught up in the carb throat and blocked the butterfly valve from fully closing. It is my understanding that on mag shutdown, he had approx 3 minutes of fuel left.
It remains to be seen if he damaged the engine by supercooling it by killing the mags inflight with that power setting, but that part was unavoidable, and I suppose the body filler did not any favors to the blower or engine in any case. The engine was about to supercool inflight one way or another. A clipped wing Bearcat with a windmilling 4-blade comes down FAST, his descent angle was relatively impressive.
