Hello, my name is ***** ***** how bad the fire was, I would look over all of the electrical on the engine. Then I would to look at would be the spark plugs to make sure that I do not have a fouled one. After that I would measure the cranking voltage from the stator and the flywheel. Should be over 180V AC on the stator and just over 1V on the trigger for each ire color.
