IGNITION SYSTEM

Ignition system on the 25B and 30H consists of flywheel magnet, charge coil, pulser coil, CDI
unit, and ignition coil.
Similar to the previous 25V and 30G, the engine has the mechanical ignition timing advance
system that works by way of the linkage.
Superior fuel economy is attained by the modified ignition timing control arrangement.
Also the system restricts the ignition timing advance when the shift is in neutral, which helps
to prevent the kickback at the engine start.
