In the classic flywheel housed magneto system, it's hidden under/behind
the flywheel itself. The flywheel in this case contains magnets embedded
into the outer rim of the flywheel which pass within a millimetre or less
from an inner laminated ferrous stator with both low and high tension
windings with a contact breaker in the LT windings,

I'm not sure how many of these basic / stationary engines have points
and so normally just use the close proximity of the rotor to the
stator to generate the spark and determine the ignition timing?
