Actually there are 2 pages. But it's pretty detailed as to how magneto's, flywheels and spark plugs work.
I hope this helps someone.
Here's a little bit:
All kart engines use magneto ignition systems. Unlike the ignition system in your car or truck, a magneto doesn't require a battery as a basic power source to run the ignition system. Instead, it relies on principles of electricity and magnetism. When you wrap wire around an iron or steel core, and then change the magnetic field in that core, you induce an electrical voltage in the wire. Magnetically speaking, as the magnetic field of the magnet approaches the field that the wire creates around the metal core on which it is wound, a "potential" develops. The rate at which that potential develops determines it magnitude. It's how a generator works. The more coils of wire you pass through the magnetic field, the more voltage you induce in the wire. Spinning the coils on the armature of the generator past the magnets induces voltage in the armature. That's what powers your trailer lights at the track, or your power tools, or whatever. But it doesn't matter which element, the magnet or the coil of wire, moves and which is stationary. In your engine, the magnets are located in the flywheel or ignition rotor attached to the crankshaft. The coils of wire into which we're going to induce the voltage are located in the coil, which in this case is stationary. So unlike the example above, the magnetic field rotates past the wire, rather than the other way around. But the effect is the same. Moving the magnets past the wire induces......
