IGNITION SYSTEM
The 25B and 30H use the mechanical ignition timing advance system, in which the base of the
charge coil and the pulser coil slides in accordance with the throttle valve opening.
Mechanical ignition timing advance applied in this system makes it easier to adjust and
confirm the appropriate ignition timing.
In addition, the ignition timing advance is restricted when the shift is in neutral, which helps
to prevent the kickback at the engine start.
