I had a well-worn 216 on a run stand in the high school auto shop where I taught for 20-something years. It wouldn't cold start with the hand crank I home-brewed, but if we warmed it up first I could crank it up that way. I mostly used the crank for static timing, setting valves, etc. No, I never let the students give it a try!
