I put the mag back on my F12 yesterday and..... couldn't get it to throw a spark with a plug that
was grounded against to head. So I held the plug wire in my hand and(nervously) cranked 'er over. I got a jolt none-the-less but oh was it weak. Any ideas on how to fix this would be greatly appreciated. I took the magnet off and it doesn't seem to have a whole lot of holding power, it will hang onto the frame rail but not very hard to pull it off.... Thanks, brian

Brian,
If the magnet is as weak as you say, I would have it recharged. That will most likely correct your problem. Weak magnet=weak spark.

THANKS.....I think I'll try getting the magnet recharged first.

I had a similar problem once on an outboard motor. It turned out to be some worn thin insulation where the points are mounted. There was no ground when checking with the meter, but as soon as the magneto put out a few thousand volts it arced through and lost almost all of the spark. I'd check everything along the high voltage circuit from magneto to plug and replace anything that looks even a little suspect.
