Was at the lake yesterday fishing, and decided to move to a different location. I started the motor up, and when I gave it some throttle it died. The motor had been running great, before this happened. The motor will idle idle just fine, But when you give it some gas its like turning off the key switch. I checked the fire and I have fire on all cylinders. While it is idling with the cowling off I moved the throttle bar on the carbs and the motor revs up. When the lever from the timing moves is when it kills the motor. Could the stator be bad?
