ARC Racing 6618 adjustable timing billet flywheel designed for Honda GX200 and 196cc clone engines. This precision-machined billet flywheel allows fine ignition timing adjustment in 1° increments, giving engine builders greater tuning control for competitive kart racing and high-performance small engine builds.
The ARC Racing 6618 billet flywheel is engineered for Honda GX200 and 196cc clone-based racing engines where precise ignition timing control is critical. Precision-machined from high-strength billet aluminum and SFI certified for racing safety, this flywheel provides the durability and ignition stability required for high-RPM kart racing engines.
The adjustable hub design allows timing to be changed in 1° increments, providing a total timing adjustment range of approximately 24°–38° BTDC when used with a standard stock key. This makes the 6618 flywheel ideal for racers and engine builders who need precise ignition tuning for different racing classes and engine combinations.
Important: This flywheel is not designed to work with a pull starter assembly. Electric or external starting methods must be used with this flywheel configuration.
