I was using Klotz Technoplate. RCS suggested that this was not the best Klotz oil for this engine. He did suggest High Qual HR1 or something similiar. He also suggested that I go to 40:1 for break-in again.

I had the sleeve honed and had a new ring put in. The engine runs at 8K with a 20x6 Mejlic, but I am using a Zinger Pro 20x8 at 6700rpm. I can fly the 106" Citabria at half throttle with just enough grouind clearence and can probably all floats later.
