Removed the stator and exciter coil. Cleaned them up and got very faint spark with the original CDI unit. I suspect the stator is NOT generating enough AC voltage to truly fire the plug. Ordered a new one. Surprisingly, the new CDI generated NO spark……
Informed the EBay seller and surprisingly they immediately initiated a full refund! Not clear if they even want the unit returned, but very impressed with the instantaneous response! Wow.
