Thank you, appreciate the feedback. I just finished tinkering with it again. I've changed the carburettor totally, put in a new diag. and gasket, new "o" ring, new rubber elbow on the carby, new gasket on air cleaner, new governor and anti-surge spring, checked the plastic manifold tube for cracks and tightness, put it back together and it still does the same thing. One thing I did notice that when assembled (not running) and the throttle slide is set to fast, there is little or no spring back on the governor vane. It is the 3.5hp Sprint motor.
