Suzuki DT75 #2 plug not firing

[Cottonp]

Have 1985 DT75 Suzuki...worked fine..one day in middle of plane engine begain to shutter down and run at fast idle. Rebuilt carbs..no help..fuel on plug but plug is clean..no spark. Replaced coil, still no fire. Other two plugs firing fine. Can stator fire on plug one and three and not two? Is there a sensor on this model that may shut down firing?

Have you checked your pulser coil resistances and outputs? You should be able to check the spark out of the engine to see if it is present.
