I've got a new Robin Subaru EHO35 engine on a BMP friction drive. The engine likely has about 30 miles on it. Under load and at slower speed, typically accelerating, I hear a knocking in the engine. At higher speeds and cruising the knocking is NOT present. Is this just because its new? Gas is only a month or so old. Do I need to treat the gas? Or is this normal or something I can expect until broken in? Performance is good, at least for new engine.
