RE: My 2300 only likes one prop
I don't think that the particles left in the engine would cause the engine to quit but merely reduce the life of the engine. I flushed my engine with fuel and collected the fuel in a bottle. After the fuel settled for a while I was amazed at the amount of particles I flushed out of the engine. I have heard reports that other engines will have machining particles also. It is my belief that the problems related to this engien stem from the carb as others have reported. A pump will not solve this problem.
