    Thanks for the input Norman. I will remove the zip ties and repost a better view of the coil.

    You need to swap 2 & 3.

    I googled "MZ202 ignition diagram". The very first hit was the engine manual, including the wiring diagram:

    If you have not changed it to this already. As I understand the wiring diagram. Each coil serves both cylinders . Meaning the engine would run with only one coil or one CDI serving. Thus the picture is wrong and 2 and 3 need to be swapped . This would allow the engine to still to run even if one of the CDI or one coil died. Dual ignition is redundant not required .

    Thanks for taking the time Norman. I swapped 2 & 3 as you suggested.
