Good advise above. What prop are you running? Is the engine in a plane or on a test stand, and is the muffler on during break in? It's best to keep it off during break in if possible. It sounds like you have run it in enough. The Moki's need to be weaned off of lots and lots of oil as soon as possible. It makes for better mid range and top end. I'm not saying to turn the needle in for the last blessed rpm, but just wean it off the oil and run it responsibly. The manual refers to oil as low as 10%, but be careful! It's a beast of an engine if you learn to give it what it wants.
