Airgap from flywheel to the coil should be about .014 or so, which works out
about the thickness of a cardboard box from spark plugs.

Coil should be dry to work.

Grounding wires to shutoff switch should be insulated, and not grounded.

We talking points or electronic?

Plug works, but no spark.

The magneto normally creates a large potential difference
capable of creating a spark to "fire" the combustion of
gasoline. Apparently, the step-up transformer which
produces enough potential isn't causing the electrons to jump
the gap on the spark plug.

I adjusts a coil near the edge of the flywheel and found
only two sparks (via high-tension wire and ground) during
a start attempt. A second start attempt results with no sparks.
A third attempt results with two sparks after a minor
adjustment to the coil.

The flywheel where magnet is embedded is left alone,
maybe this could be the problem.

So as the flywheel goes around, the magnet passes by the
coil. And should create a rapidly changing magnetic field
which induces a current in the coil, but this isn't happening.
Is a magneto ignition system good only for airplanes? What
are some possibilities I can do to achieve a consistent
spark?
