Ha, ha, I figured out the mystery!

It turns out the "L" (CCW) mag really IS a CCW mag. Someone, (I'm glad I don't know who) stuck this thing on the Continental engine, and probably gave up when they couldn't get a spark out of it. I turn this thing CCW, instead of CW, and I get a spark a half an inch long! There's nothing wrong with the magneto or the impulse mechanism, or anything else. It's just the wrong mag for the engine, period. I found this Shorthood in the weeds and asked the owner if I could have it. They said sure, and didn;t know or care what it was. I've overhauled the whole generator end of the machine, and was just now getting around to the engine end of it, when I couldn't get a spark out of the magneto. I remember thinking the Int'l mag on a Continental was WEIRD, but I guess it was just there for show, (or something). I'll stick this mag on the shelf, and chalk the whole adventure up to "continuing education". Thanks for all the help everyone.

Today's Featured Article - The Day Mom Drove the 8N - by Brian Browning. My Dad was wanting to put in a garden but couldn't operate the 8N and handle the old horse drawn plow he had found and rigged up to use with the tractor. Well, he decided to go get Mom out of the house and have her drive the tractor while he walked behind the plow. You got to understand that while my Mom is a hard worker who will always help whenever she can... she had never operated farm machinery before that day. Dad got her out there, explained how the clutch was the same as in our o ... [Read Article]
