Chainsaw Repair

Running fine last week, died (think I ran out of gas), refilled, never started again.  No hint of a spark across new (or old) plug, out of the cylinder head, grounded to metal, with kill switch wire completely disconnected.  Armature/flywheel magnet air gap tried at 0.010" and 0.014"  This ignition system is simple, just flywheel magnets, armature/coil, plug wire, and plug.  Several websites said if it doesn't spark, the armature/coil is bad.  530 039128 coil no longer available new, so I bought a used one from Chainsawr.  That one doesn't spark the plug either.  The plug will spark hooked up to my car ignition, and a known good car spark plug will not spark on the chainsaw coil.  I used a cordless drill to spin the flywheel to make sure it was going fast enough to allow a good spark.  I used the first two testing for spark instructions at https://store.chainsawr.com/blogs/tuning-and-repairs/1125992-how-to-test-a-chainsaw-ignition-for-spark (spark the plug in air, check for pulses), but not the 3rd one that says hold the plug in your hand and see if you get shocked.  The second method puts a DC voltmeter on the 20 volt scale and looks for pulses to the spark plug boot.  I get those, but no spark on an actual plug, so it's trying to do something but it must be too weak.  Obviously 20 volts is not enough to jump a spark gap, so I wonder why the test specifies that voltmeter range. 

So I measured the resistance of the old and replacement coils; both exactly the same at 7.3 kohm secondary from ground lead to spark plug boot terminal, and 1.3 ohms primary from kill terminal to ground lead.  (The coils have a ground wire lead coming out that is bolted to metal, in addition to the kill terminal.)  Anyone know if these numbers seem correct?  Both bad coils?

Unbelievable.  I stroked the flywheel magnets with another magnet, and the saw fired up.  I've seen it written and been told that the magnets never go bad, though I have seen it written that a whack to a magnet can make it lose its magnetism.  Go figure.

Thank you.
