The flywheel key is the component on outdoor equipment that keeps the flywheel connected to the crankshaft. Over time, this key may become damaged or broken, particularly if the engine experiences a forceful stop, like hitting a large stationary object. If the flywheel key breaks, the engine will not start. A slightly damaged flywheel key is noticeable through symptoms like misfiring, backfiring, or having no power. If any of these are occurring, the flywheel key should be replaced to prevent complete engine failure.A flywheel puller tool is required for this repair. Make sure the engine is cool before working on the flywheel. Wear safety gear, including gloves and eye protection. Disconnect the spark plug and remove the blower housing. Remove the flywheel mounting nut and set it aside. Take the recoil starter cup off the mower. Use the flywheel puller to remove the flywheel and access the flywheel key.

An in-line fuel filter prevents contaminants from entering the carburetor and engine. In any engine, if the in-line fuel filter becomes clogged for whatever reason, the fuel cannot flow freely to the carburetor. This can prevent the engine from starting or may shut off the engine during operation when the fuel supply is interrupted. Without any gas, the engine cannot run. Any number of things can cause the filter to become clogged. Examples of typical clogging culprits are lawn clippings, mulch, stones or rocks, or contaminants from poor-grade fuel. If your engine stops or won’t start up, remove the old in-line fuel filter, and replace it with the new one. If this does not fix your problem, the carburetor may need cleaning or replacement due to damage from the contaminants, as well. The outside material of this fuel filter is plastic, while the inside material is comprised of a filter component interior. This in-line fuel filter is manufactured by Briggs & Stratton. It is compatible with engines on lawnmowers, lawn tractors, snowblowers, and generators manufactured by Briggs & Stratton, Craftsman, Cub Cadet, Murray, MTD, Simplicity, Snapper, Toro, and Troy-Bilt.

This oil seal is a genuine OEM replacement part designed for use on a wide variety of small gas-powered appliance engines. Although small, an oil seal is an important part of the oil cylinder assembly as it prevents oil from leaking into other parts of the engine. If oil begins to leak into the engine, it can corrode other parts or even pose a fire hazard. Therefore, it's important that the oil cylinder is tightly sealed to prevent any damage to the engine. Seals can wear out over time, especially if exposed to heat. Heat will cause the seal to shrink, effectively unsealing the oil cylinder. Before making this repair, be sure to drain the oil cylinder of any oil and be prepared for an involved replacement process. This part is compatible with Toro, Murray, and Briggs & Stratton appliances and is sourced from the original manufacturer. It ship individually of other hardware.

This is an inline fuel filter and is an essential part of a fuel system. This part can be found inside the fuel tank or fitted into the fuel line. The fuel filter is responsible for straining particles like water and debris in the fuel so that they won't reach and clog the combustion chamber and eventually reduce the engine's performance. Annoying sputters when starting equipment and uneven idling are incidents that may be related to a clogged fuel filter. To remove a fuel filter, first cut off the fuel supply and then slide the fuel clamps away to remove the filter. Remember to work in a well-ventilated area, with no open flame or fire source, when installing this component. This part works with lawn mowers, snowblowers, tillers, generators, wood chippers, and others with small engines. It is compatible with brands such as Briggs & Stratton, Craftsman, Toro, Cub Cadet, Murray, Lawn Boy, Snapper, and Simplicity. This is a manufacturer-supplied OEM replacement part and comes as an individual component.

The pre-cleaner is usually placed over the actual air filter and is designed to catch debris and emissions before they enter the air filter, which will then clean the rest of the air going through the machine. The pre-cleaner can become dirty and clogged with debris as a part of regular use. As such, it should be replaced as part of a regular maintenance routine. However, it may also need to be replaced intermittently if it becomes clogged. An air filter or pre-cleaner is clogged if the engine will not run as smoothly as it should. Always check the manual for compatibility and part numbers, as well as any safety and replacement recommendations. This unit can be installed dry and does not require any special preparation or pre-oiling. This part replacement is suggested as maintenance because you may not be able to tell it is dirty until it is removed from the air filter, but a replacement is easy to perform. This OEM replacement pre-cleaner is compatible with various models of air filters in Briggs & Stratton engines.
