Quick update, I cleaned the pistons and heads. All needle bearings got a direct shot of 2 stoke oil as did the cylinder walls and rings. The engine is all back together and installed back into the airplane. When turning it over with the prop there is no clicking noise and it has just as much compression feel as any of my DA 150 engines did. I still need to hook up the plumbing and exhaust. That will have to wait another day, tomorrow I decided I'm going to take my old reliable Aurora out and de stress flying it. I hope to post a video of the run up on Monday.
