A good friend just put that very same engine in a Tower Kaos. He picked the engine up some years ago in a trade as he owns a LHS. He just took the guy at his word that it was just barely broken in, but done right, then never got mounted to a plane. Charlie has sat on it properly stored for all these years until last week. We took it out for a maiden flight on th new Kaos & it fired right up. Just the slightest bit of tuning after warm up had it running great. The plane flew magnificently, no dead-sticks all day & it had all the power the Kaos could want. It turned out to be a great engine. Charlie was very pleased with it. I hope you have similar results from yours.[sm=wink_smile.gif]
