I'm considering this engine completed. Took me a couple of days less than a month from start to finish. After the last video, I opened up all the inlet air passages to 3/16" and also added a single o-ring to the piston. With those mods and a little breaking in, the engine will now coast between 10 - 12 revolutions between power strokes. Don't think I can do much to improve it now except maybe bore it out a little, but I think it sounds fine as is. Here's the final video:
