Other then the rough idle (sounds like its missing) it runs awsome all the way up to full throttle, pushes my little 14 foot aluminum to 24.5mph with 2 adults weighing 200 pounds each. I replaced both of the spark plugs and I am running premium fuel with a 50:1 mix of high end sonic 2 stroke oil. I also ran some sea foam through the carb intake and the gas.
