Here is a genuine replacement governor shaft that can be used with many types of small engines. The metal governor shaft is used in the cylinder cover to help hold the governor spool and the gear.

However, there may still be a need to replace it at some point. It could have become corroded or damaged, or it could have become lost during another repair. Regardless of the reason, owners will want to replace it sooner rather than later. A wrench and pliers will be needed to make the replacement. This is an authentic OEM part that is the same as the original on the machine. It is sold individually. The part can work with many makes and models of lawnmower, snowblower, log splitter, generator, wood chipper, pressure washer, and other small engines.

This is a flywheel key manufactured by Craftsman and also used by Tecumseh for many of their small gasoline powered engines, particularly lawn mowers. A flywheel key is a part that sits between the flywheel and the crankshaft of the engine. When the engine turns over, the flywheel causes the equipment's moving parts to turn, such as the blades of a mower. A flywheel key is designed to sheer off or break without damaging the flywheel should the mower blades hit an obstacle. If the engine will not start, starts but does not have full power, or throws out a lot of engine oil and smoke, the chances are the flywheel key is damaged. If there is a tremendous amount of backlash when the user tries to pull the starting rope, that also is a sign of a damaged flywheel key. When a flywheel key is damaged, it causes the spark plug to fire out of synch with the proper fuel/air mixture coming into the cylinder. Remember when replacing the flywheel key, it is essential to use a replacement part like this one that is a genuine OEM manufacture part. It is identical the original.
