The impulse-coupling alone should give you a hot enough spark to see if the mag is working. If you have something that will grip the drive, you should be able to make it click over enough to see if there is a spark. The impulse was designed to make up for the very weak spark that would be produced at hand-cranking speed. Early airplanes, and some cars (Model T Ford, for example) did not have impulse couplings, and there were a couple of ways to provide the spark needed for hand cranking. Some airplanes had an auxiliary generator that the pilot spun to give enough spark while a mechanic turned the prop. The Ford T in its later life had a battery that could be turned on for starting current. The very weak spark made by hand-cranking was one reason people resorted to trying to spin the crank, to get a hotter spark. Problem was, sometimes the engine got cantankerous, like a mule, and kicked. The result was a broken arm. Happened to my father back in the 20s when he tried to spin a Ford T.

And I think Dad was ready for some automation too. And so it was that we acquired a good, used J. I. Case, wire tie hay baler. In addition to a person to drive th
