15 Hp gamefisher model 225-581501 runs fine a little choppy but idols well but when you take off it doesnt feel like a 15 hp..? Cleaned the carb could it be electrical?
Does your Gamefisher have points? If so, they would be located under the flywheel and do need replacing. The other thing is that these engines carbon up over time and need to be decarbonized. Have you ever decarbed the engine.
