[QUOTE="Pappy, post: 177249, member: 3278"] Remove the carb and soak in a good carb cleaner. Go to a dealer and get a carb kit for it or if you have to get one from Napa (aftermarket). Always have your model number handy when ordering parts. Do not try and continue to run the engine at high RPM with a lean condition or your next issue will be a seized piston. Fix the carb! Another tip, no need to run any higher octane in a production outboard than 89 octane. You will actually build more (and more sustainable) HP with 89 than 93 as it will take better advantage of the two stroke spark curve. Good luck with your repair. [/QUOTE]
