Yep, it's another blue coil POS failure. After searching many threads, there are a lot of guys that have replaced this coil with a Husky one from China, but the part numbers seem confusing. I can find 2 coils that both seem to be for the same family of Husky saws. One is 503620203 and the other is 544018401. Can anyone verify which is the right one? There is also a reference to another one 503901401 but I can't find any info on it. Thanks for any help.
