It is amazing how people will blame a engine manufacture for their plane crashing! Saito only produces four stroke engines and it is hard for me to believe that they don't know how to properly build a four stroke engine. I have had many of their engines over the past ten years and have yet to loose a plane because of the engine being a Saito. A very foolish statement to make in my opinion. Is their a engine manufacture that gurantees their engines to never fail? I sure would not fly a airplane with the engine not running correctly. You are just asking for trouble. Would you get in a airplane knowing that the engine is not running correctly?
