2. Construction
2.1 Outline
This GK 352 type flywheel magneto applys a new control
unit called "Capacitor Discharge Igniter", which works
alike with contact breakers of ordinary flywheel magnetos.
Thus, this flywheel magneto does not use any contact
breakers and conventional condensers.
GK 352 works as electric power source for said CDI unit.
Hundreds voltage generated by it is stored in a primary
condenser and abruptly discharged to a primary coil of an
ignition coil in a timed relation with an engine operation.
Then, a secondary coil generates high voltage electricity
for igniting gaseous air.
