The coils run around $50. Your machine may not even have a CDI/ECM. It may also be the voltage regulator which can also run around $50. Just to let you know, I am no mechanic but, there are not many parts that make up the electrical system on these engines.
Someone else on here may be able to give you better advise than I can.
We can get any of these parts I've mentioned and possibly at better price than the listed price I gave above.
