my 40la engine that i put on my 25 size me-109 inverted seemed to be having less rpm's and that it has reduced horsepower...i suspect that it's because that the engine is inverted and because of how the fuel leaks out of the carburetor when it is inverted....is it just me or is this common to some of you guys too?...Can anything be done to correct this or are two strokes really weaker when it comes to being inverted?
