It runs, I used a Sullivan Dynatron as Dennis did, it started on about the 3rd compression stroke, as Dennis also said, it's cold natured although it required a full turn of compression from where it started so it may not be so cold natured next time. I managed to get the J-Tec muffler on it by grinding a couple of washers flat on two side, you can see one of them. It definitely needs a larger prop, I had to bury the compression screw to get 6,650. Boy is it smooth, acceleration is nearly instant even with the heavy Classic 20x10. Well, now all I need is $375 bucks for the plane, 50 bucks for a Just Engines Jen-C/Biela 21x12 prop and 54 bucks for a bisson Pitts muffler. Nothing to it, beyond a small miracle.
