NEW 6607-P 3 HP Diameter Predator Flywheel This new ARC billet, SFI Certified flywheel utilizes the same outer body of our standard billet 6607 flywheel, but it has been fitted with an adjustable timing hub specifically designed for the popular Harbor Freight Predator 212cc Engine. The keyway is in the stock position when the flywheel's indexed adjustable timing hub is set to the negative side of the index range. Index marks are in 2° increments which allows up to 14° timing advance from the stock position (25°-39° range). The flywheel weighs 3.5 lbs, is 5 3/4" in diameter. It has a super-strong rare earth neodymium magnet. Requires #5982 coil bracket.
