Well the emulsifier O Ring has definitely stopped the fuel delivery issue as I get nice 1 pull starts with no chugging coughing or smoking.
I confirmed this morning that the butterfly in the carb operates freely and is no binding.
I have include a photo of the governor linkage and to the best of my knowledge it is not binding with the breather hose. Everything moves freely as it should.
The mower is still running to fast (you could call it holding the throttle open as I cant get an idle at all. When you move the throttle to the full speed position the actual speed of the engine doesn�t change. Its still full speed.
