Parts for Briggs & Stratton 12A112-0921-E1: Electric Starter Parts

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 rocker switch is designed as an identical replacement part for select models of blower/vacuum units. The rocker switch is also known as a power switch or on/off switch and it is what controls the current to electric blowers. The switch is made of plastic and metal. This switch may become worn and not function well after regular use because of the repetitive motion of turning the machine on and off. In some cases, the switch may experience electrical malfunctions that could present a fire hazard or keep the unit from working at all. In the event that the switch is damaged or defective, it will need to be replaced. This genuine OEM replacement rocker switch is manufactured by Briggs & Stratton. It can be used with more than 150 models of machines from Briggs & Stratton, Toro, and Vanguard. This part is made of durable plastic and metal components and is sold as an individual unit. It plugs into the pressure washer via wires, but a screwdriver may be needed to assist in the installation. Always disconnect the power supply when working on electrical components and wear gloves for safety.

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.

This replacement part is a switch key. This is a genuine replacement part made by Midwest Engine. This part is commonly found installed within certain lawn mowers and is able to ensure that the user can turn the machine on and off according to the desired settings. A new switch key might be needed if the current one is unable to turn the machine on or off. This can be caused by normal wear and tear over time. If the key is no longer working, it can be due to this part being damaged. This should be a fairly simple repair and should only use common household tools. This is a genuine OEM replacement part. This part is sold individually and is sourced directly from the manufacturer.

This key set is designed as a replacement and it is specifically for select models of snowblower. The ignition key is used as a means to turn on the machine. It makes using the machine easier than having a pull-start engine. This key is red, which can be helpful in case it was dropped in the snow – it will be easy to find. The key provides more safety for the machine, preventing unauthorized people from using the equipment. The key may need to be replaced for certain reasons. The current key could become lost, or it could be damaged. If it is damaged, there is a chance that it might no longer fit properly into the ignition. Owners should get a new key rather than risk breaking a key in the snowblower's ignition. This is a genuine OEM key set right from the manufacturer. It is sold individually, and some might want to buy more than one at a time, just to have them available. The keys are compatible with certain snowblower models from Briggs & Stratton, Toro, Murray, Snapper, and Simplicity.
