A very simple single cylinder 4-stroke spring bike engine. Very lightweight and not very powerful. It seems to be producing over 200 watts.

The timing is angle sensitive so it would work backwards upside-down. Simple fix but it's useless anyway so I didn't bother. Uses Scene.my variables because I'm a noob.
