I've reached that stage in life--almost "8 decades," which makes it sound better than it really is--when I think I might have a few odds and ends of knowledge that could help younger fellers (we old timers always talked like that).
Not long ago, I saw a guy spinning a crank on an old tractor, on YouTube. I wrote a comment, suggesting it was a good way to come away with a broken arm if the engine kicked back (my father had his arm broken this way, and I decided early on never to spin, just in case the impulse didn't catch--had seen big tractor engines go backward, too, and boy is it impressive!). The guy was furious and posted a comment AND sent an e-mail to me, calling me a "know-it-all" and saying that I was calling him stupid.
Well, anyway, this isn't directed at anybody in particular, and I sure ain't calling anybody stupid (I wasn't then, either). But....if you crank, keep your face out of the way of the crank AND pull up. The impulse coupling provides plenty of spin for a hot spark.
