Have any of you had this problem and the engine idles well. The symptoms appear as the throttle is increased and worsens at WOT, black smoke, runs rich, uncontrollable RPM’s, mis firing, back fires, and hard to start. This is on my Simplicity 3415H with a 15 hp Briggs.
I was cutting grass yesterday with no problems, never hit nothing, then all these symptoms started. Since I’ve had this, the carb has been a major pain, the adjustments never stay, it has the typical flo jet gas leak from the emulsion tube no matter what I do to it. When I got it back to the shop I started to adjust the carb thinking that was the problem but no matter what I done to the carb it ran the same. I might start out checking the head gasket, then pull the head then check the valves before I check for a sheard flywheel jey.
