This is a rotating screen that protects the lawnmower engine from debris and dirt that could damage the engine. It is an authentic OEM replacement part sourced directly from the manufacturer for use on a variety of lawnmowers. If the screen becomes damaged or broken, dirt and debris could damage the engine or other critical parts. Without the screen, small animals and insects, like little birds and bees, could get inside the engine cavity and make nests. This could be detrimental to the engine and to the animal. During the inspection, if the screen is found to be damaged, it should be removed and replaced. A Torx driver is needed to remove the screen. Wear work gloves and make sure the spark plug has been removed from the lawnmower. Remove the Torx screws and set them aside for use on the new rotating screen. After removing the screws, the blower housing has to be removed in order to remove the screen. After the screen is removed, clean the engine cavity with a blower to remove any dirt or debris. Install the new cover, then reinstall the blower housing and spark plug.This rotating screen is made of durable black plastic and is sold as an individual part. It is designed for use on lawnmowers manufactured by Toro, Briggs & Stratton, MTD, and Craftsman.

Flange screws have a flange located near the top of the screw, which helps to distribute the connection force over a larger area to reduce potential damage to the machine. It also allows the screws to be used in oversized or irregular holes, and it helps to ensure they stay in place. This flange screw also has a hex top. Screws can last for a long time. However, they may become corroded or worn over time and need to be replaced. They could also become lost and need a replacement. Without all of the screws in the proper places in a machine, it could vibrate too much, which could render it less effective or unsafe to use. The flange screw is a genuine OEM part that can be used with many types of machines including lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, generators, wood chippers, and other small engines. The screws are compatible with Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn-Boy, Snapper, Simplicity, and MTD.

This is a replacement ignition coil that is used in various types of small engines. Other names for this part include the ignition module and armature-magneto. The purpose of the ignition coil is to provide electric current for the ignition system. This electrical current is then sent to the spark plugs, which allow the engine to start. The ignition coil is made from metal, but it is surrounded by rubber insulation. The ignition coil can start to wear out over time. It could become damaged due to corrosion or simply because of wear and tear. If the coil has problems, the engine will have trouble starting. Sometimes, it will not start at all. The owner will want to replace the ignition coil at the earliest signs of trouble. This genuine OEM replacement ignition coil is sold individually. It does not come with a spark plug boot, which can be purchased separately for those who need it. The ignition coil can work with the engines of many models of lawn mowers, as well as other small engines. Compatible brands include Briggs & Stratton, Toro, Cub Cadet, MTD, and Simplicity.

This is a screw that is used in many types of lawn and garden equipment, including lawnmowers and wood chippers. It comes with a black finish and is made of durable metal. The screw can be used in many locations on a tool to attach two components together. Screws can also be used in tandem with nuts, but the two components should have the same threading and finish.Screws can become damaged, break, or be stripped and will need to be replaced. Corrosion, extreme temperatures, and unexpected stress can all lead to issues with a screw. A visual inspection can indicate whether the screw should be replaced. If it does need replacement, a screwdriver can be used to remove the original screw. The new component can be placed and tightened.This screw is a genuine OEM replacement part that is sourced directly from the manufacturer. It is sold as a single component. The screw can be used with many types of lawn and garden equipment, including lawnmowers, tillers, pressure washers, leaf blowers, edgers, generators, wood chippers, and snowblowers manufactured by Briggs & Stratton, Cub Cadet, Craftsman, Murray, Wheel Horse, Lawn-Boy, MTD, MasterCut, Simplicity, and Toro.

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.
