🔌 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

📦 Condition

• Genuine used part

• Removed from running engine where applicable

• In good working condition unless otherwise stated
