A magneto armature, also called a magneto charger, is a device that provides electric voltage to a spark plug in lieu of a battery. Small gasoline-powered engines that do not have batteries use magneto charges to produce the power to fire a spark plug, combusting the fuel mixture and turning over the engine. More than 150 different gasoline engines, primarily those used by snowblowers, leaf blowers, vacuum, and mowers, use this type of magneto armature. While these devices can last for the lifetime of the engine it is attached to, magneto armatures are exposed to extremely high voltage and they do occasionally break down as a result of extensive use. If an engine simply will not start, it's a good idea to use a multimeter to test the magneto. When replacing the magneto charger, purchase a replacement such as this genuine OEM manufactured replacement part that is built according to the same specifications as the original part. Typically, the magneto sits atop the engine housing and is attached to the engine coil. When checking the magneto, it's a good idea to test the engine coil as well, as the two may be replaced at the same time. This magneto is compatible with engines built by Toro and Briggs & Stratton.

This genuine OEM part is a rocker switch for lawnmower engines. A rocker switch is the component that allows the user to power the engine. If the rocker switch is no longer functioning and not turning the engine on and off as intended, it might need to be replaced.

The stop switch, sometimes called a kill switch, is triggered to stop the engine when the operator is no longer on the seat ,This is important for safety.

The replacement part is compatible with a range of brands, including Midwest Engine, Toro, Craftsman, Briggs & Stratton, Lawn-Boy, Murray, Snapper, and MTD.

This genuine OEM replacement part is a spark plug terminal for a wide variety of small combustion engines. In a combustion engine, the spark plug generates a small electrical charge that creates enough power to start up the ignition and engage combustion. The plug connects to the ignition through the terminal. Spark plugs generate and then pass a small electrical current through to the ignition. Usually, the main issue with spark plugs is that this current hyper-extends and ends up frying the spark plug. However, if the terminal is damaged, the charge will not pass into the ignitor, and the engine will not turn. If the spark plug can carry a charge but the engine still won't turn, it's likely the terminal that needs replacing. This is an easy repair because the terminal should just snap on and off. If stuck, a pair of needle-nose pliers should make it easier. This high-quality replacement part is compatible with engines from Murray, Toro, Lawn Boy, and Briggs & Stratton. It is sourced from the original manufacturer and ships individually.
