Thanks for educating me. I gave thought to the magnets on the flywheel but don't know how about testing that.You do know that you can't reliable test the primary side of CDI coils don't you?
Also provide the SN of the blower as there is a couple coils used in the later models.
Also early coil was superseded from A41000420 to A040000030 which now a coil and flywheel set which explains the high cost.

I see the set is A040000030 but a coil is A411000420.You can only take things on YouTube with a grain of salt. Sorry self contain electronics can not be tested with an ohms meter. Doesn't matter what someone one YouTube says. It requires a very expensive tester that Echo has. For us in the field it is plug and ply testing. Otherwords either the coil works or not when installed.

Could you explain what NLA and TTI mean?The A411000420 is no longer available hence the supersede from Echo. If you order the A411000420 the vendor will be forced to supersede the part to the current part and charge accordingly. Or simply return your order as the part is NLA.
Echo would not have superseded if they still had the A411000420 available. They could have just NLA the part and left you with scrape metal.
And many online vendors simply have not updated their systems until someone order the part. I get this a lot. I just got a refund from Jack's where I had ordered some TTI parts to only find out they are now NLA. My customer going to be pissed but it is not my he shammed the charger on the concrete floor in a fit of rage.
Thank youNLA = No Longer Available
TTI = Techtronic Industries.
