Husky 346XP not starting? Has fire, plug wet. Won't kick off with ether either

Had a husky do the same thing spark, wet plug and would happen on rainy/humid days mostly. Turned out to be the coil but had me stumped for awhile.

[Al_Smith]

Well yes a bad coil would do it .

Now here ya go ,one for the books .I have a little Echo string trimmer I thought had a bad coil,replaced it,no spark .Not the coil at all ,weak flywheel magnets .

So the so called experts say you cannot remagnetize them .Funny thing just this afternoon I did and it worked . 8)Never say never .

Pray tell, how did you manage such a feat?

[Al_Smith]

Blind luck is all I can say .One magnet was weak of a three magnet set up .In other words two circuits .The charging circuit and the trigger circuit .

I determined the polarity and joined two ALNICO magnets so as to produce a stronger field and "stroked" the weak magnet for  about 30 seconds and left the magnet attatched for about 5 minutes .It was the last magnet in rotation so it must be the trigger circuit .

Surfing the net they say it can't be done but the thing worked .You never know until you try . ;D

Not being an engineer type, I don't see any reason why you could not do so. There are certainly naturally occuring magnets, but by and large anything we would be using today is manmade. I just wanted to know how you did it, not doubting you at all. How did you determine that one of the magnets was bad?

[Al_Smith]

I used a little screw driver .The center magnet I think is the north pole and is the strongest .The outside two are south poles .The leading south had a lot more pull than the trailing south .

I can only assume the magnets were soft iron which has a great potential for magnetic retentivity and is also very easily magnitized .I further assume the two south poles might have been less mass than the north which would explain the difference in pull .

I'm not certain if the actual ignition is a CDI or a thyratron fired thing .No matter .At any rate it takes a negative pulse in relation to the charge circuit to fire it .< electronic theory gobble-de-goop .

Mr Al Smith I'm not the sharpest tool in the shed and really admire your fix it ability. Great job and thanks for sharing 8)
