You know whats really funny is that reading some of the posts here you would imagine there was something pretty wrong with the engines in question..flaming out non stop, lack of power, wont idle...inconsistent tuning.....everything to me as a professional that would signify engine damage.............. However you go read the classifieds that said person made over those engines and all you read is engine runs excellent, low mileage, tons of power, only 1 gallon of use, like new condition......... Now I am not singling anyone out here as this happens all the time...But it is interesting and definitely worth noting.... anyways I talk to many others in the engine industry and we all see the same pattern and cycle over and over...
