We use 91 octane mogas and try to keep it fresh. Flat and level RPM at 3500 feet is 5800.
I don't know what position the carbs are in but when I gapped the plugs last I did them on the tight side of the range. So maybe that is a factor. We don't have EGT gauges, but it looks like maybe we should.

Gary, isn't that way high RPM for straight and level?
Yes, we usually cruise about 5000-5400 RPM, but for testing purposes ran it hard for a few minutes. I think we need to tighten the baffle material between the air scoop and the radiator so so air leaks in order to drop the coolant temps a little. Our oil cooler is too big so it always runs cool.
