It is a Four stroke engine. The first stroke is exhaust then the next stroke is intake compression of gas and magneto fire. The mag fires on every other stroke on a four stroke. 4:27
Alan's cars are absolutely fascinating. Since wooden the frame is flexible to some degree, and the starter not being physically attached to the engine is it possible that the clearance between the ring gear and the nose of the starter gear being .030" do you see a remote possibility where the two gears might come in contact when not intended? Thanks to both of you for all that goes into bringing this ' historia mechanicus' to YT.
That’s a great observation. My thought is that since the starter gear retracts when not in use, it will be okay. I’m going to ask Alan what he thinks in an upcoming interview… Thank you for your comment!

Great job Alan!
Thanks for the kind words!
Alan, so satisfying to see your work on these antique automobiles. Thanks for keeping them alive and running. Best regards from Sweden
Many thanks!🙏

You have to pull through two strokes of compression to fire the magneto? How does that work.? Is it a two cycle that hits every other stroke?
Magneto needs an impulse like many hand crank engines.
