What happens here

Leonard displays the half-scale piston, explaining that it was originally a production piston from a Yamaha 125cc scooter. He adapted it for the miniature engine by modifying the wrist pin hole to achieve the correct deck height and rod length, demonstrating creative material adaptation.

Goal: Illustrate the adaptation of a scooter piston for a miniature engine.

Tools and materials

What they say

Hide

the cylinder block fits. I have n't put the little pins in there yet. They, well, they'll spin. But like I said, I turned it over, and it gives a spark to the spark plugs. Connected the ignition coil and everything . I turned the drill and it sparked the spark plug. What is the ignition order? 1-5-4-2, 6-3-7-8. Yes. Is this standard Ford procedure for that time? Ignition order. When I look at the engine, I see the numbering like a Chevy. I don't speak " Ford". So I kind of have to translate it.
