Ok currently Im looking at upgrading my engine, because It is slowly dieing on me. And I wants more speed! I went out earlier today and my clutch size on that engine is 2" diameter, and the mounts were 2 1/4" in a square. I want something 40cc+ to purcahse, that they sell HP carbs for and is pretty popular. None of the Bluebird or the Active engines will fit, because they are 3", 2 3/4" mount. If I bought an engine from www.northerntool.com what type of output shaft should I get on it? Thanks,
Ryan
