🔌 Function

The flywheel provides rotational inertia, starter engagement and magnetic flux for the stator and pulser-coil assemblies. These systems generate battery-charging current and ignition-timing signals.

⚠️ Common Signs of Failure

• Starter teeth are worn, chipped or missing
• Internal magnets are loose or cracked
• Battery-charging output is low or absent
• Ignition timing becomes unstable
• Flywheel rubs against the stator
• Crankshaft taper or keyway is damaged
• Excessive flywheel runout or vibration
