This is an air filter that fits a variety of small gasoline-powered engines. These engines, which are primarily used as lawn tools, are often exposed to a great amount of lawn dust, dirt, and fine debris. This type of debris can clog the air intake quickly if it is not filtered out. This item is a foam filter, designed specifically to prevent yard waste from clogging the small engine's airflow. Periodically, even the best air filters are subject to so much particulate that they become unusable and need to be replaced. If a small yard tool engine will not start or if it “cycles” fast and slow, detach the air filter housing and start the motor to see if the engine runs properly. If it does start and run, do not use the equipment without a proper air filter. Replacing the air filter is a matter of making certain the engine manifold has cooled, then removing the muffler and air filter housing. The old filter is easily removed and discarded. Reverse the steps to reinstall the air filter. This replacement filter is a genuine OEM manufactured part, guaranteed to meet the same standards as the original part. This filter fits 150 different yard tools that use Briggs & Stratton gasoline engines.

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. If the stop switch is not functioning properly, inspect it for damage and replace it right away. Operating a machine without a functional stop switch can be dangerous. The stop switch is a genuine OEM part, and it is sold individually. The switch can work for many types of equipment including lawn tractors, lawnmowers, log splitters, wood chippers, pressure washers, and tillers. The replacement part is compatible with a range of brands, including Midwest Engine, Toro, Craftsman, Briggs & Stratton, Lawn-Boy, Murray, Snapper, and MTD.

The spark plug boot is a rubber piece that is responsible for connecting the spark plug to the spark plug wires and completing the connection. Spark plugs are necessary to create the engine spark that will start the motor in lawn equipment and other small engines. The boot holds the terminal and keeps everything protected from the elements and insulated so that it continues to work correctly. If the spark plug connection seems weak or if the existing boot is damaged, this replacement could provide the solution. This durable rubber boot will insulate the spark plugs and help any small engine run better. This spark plug boot replacement can be used with a number of Briggs & Stratton engines and is compatible with hundreds of different machines from Toro, Lawn-Boy, and Briggs & Stratton. This boot replacement is sold individually as a single piece and does not include the terminal or any other housing or materials.

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 spring brake is a genuine Midwest Engine part that can be used as a replacement part for outdoor appliances with small engines, including lawn mowers, chipper shredders, snowblowers, and other such appliances. Spring brakes are a braking system employed a large, coiled spring that is kept under high tension; the control valves attached to the spring brake are the mechanism by which the spring brake is released.If the spring brake has been damaged, is malfunctioning, or is in a state of disrepair, this will manifest in the form of a sudden, volatile eruption from the air brake chamber. This is a dangerous state for a small engine, so repair should be conducted immediately. Additionally, a new spring brake part should be ordered before any attempt to use the appliance without a proper repair. Remember to always wear gloves when handling, repairing, and operating outdoor equipment, and stay safe around the small engine of the appliance if the spring brake has malfunctioned and caused a dangerous situation.This spring brake is compatible with the brands Briggs and Stratton, Cub Cadet, and Toro.

This is a small engine brake replacement from Briggs and Stratton intended for use with lawnmowers. A well-maintained brake system is a must-have for all outdoor equipment with engines. If the brakes are working properly, they should generally stop any engine as well as any attached equipment (such as cutting blades) within a few seconds. If the user has stopped using the machine, or if the user has released the break bail, this should also trigger the brake system to shut the engine down. If the engine operates for more than a few seconds after braking, then the brakes are likely in need of a replacement or adjustment.This process should be taken care of urgently as it poses a safety risk if it goes unchecked. Brakes, brake pads, and all supplementary braking mechanisms should be evaluated routinely for any flaws or issues, even if those issues can be taken care of easily like unclogging debris.This brake is a genuine OEM part sourced directly from the manufacturer. It is sold individually. The manufacturer of this part is Briggs and Stratton.
