This fuel pump is a genuine Midwest Engine part, sold individually. This fuel pump can be used as a replacement part or a lawn tractor. The purpose of a fuel pump is to provide a passageway for fuel to channel through the fuel line and into the fuel tank.The fuel pump of a lawn mower or a lawn tractor might eventually have to be replaced in the event that it suffers damage and cannot perform its crucial function. If the fuel pump has been torn, scraped, punctured, or eroded from general wear and tear with long-term use or as the result of a direct impact with a hard object such as a rock or a curb, the component should be removed and replaced by this genuine OEM replacement part. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This is an OEM part sourced directly from the manufacturer. It is sold individually. This fuel pump is compatible with the following outdoor appliance brands: Midwest Engine, Briggs & Stratton, Cub Cadet, Simplicity, and Toro.

Seals the air cleaner to prevent unfiltered air and debris from entering your engine. Replace if cracked, compressed, or causing rough running.

Spark plugs work by providing an electric spark in a combustion chamber, igniting the mix of fuel and air that allows the engine to turn and propel a drive shaft. Insulated with ceramic to make sure the electric charge flowing through it is properly discharged, the plug is screwed into the cylinder head. The movement of the piston sucks fuel into the cylinder until it reaches the optimum level, the compression triggering the spark plug to send a pulse that ignites the fuel and pushes the piston to the back of the cylinder. This process is repeated hundreds of times a minute in an internal combustion engine. Eventually spark plugs simply wear out, particularly if they are not properly gapped, if the fuel mixture is improper, or the engine is subject to excessive use. This plug is compatible with most lawnmowers, small engines, and pressure washers made by Briggs & Stratton, Cub Cadet, and Toro. The plug itself is a guaranteed OEM part and is sold individually.

This is a genuine intake gasket replacement that is designed for use in certain lawn mower engines. This specialty intake gasket is what is responsible for creating the seal between the carburetor and the breather tube so that no gases or fluids leak when they pass between the two. This gasket is subjected to constant high pressure, vibrations, and extreme temperatures, and over time it will need replaced. Gaskets are generally considered a part of routine maintenance on most engines, and many owners will choose to keep a few extra on hand in case of an urgent repair need. This genuine OEM intake gasket is manufactured by Briggs & Stratton and designed to offer an identical replacement for the original gasket that came on the new unit. It is compatible with lawn mower engines in models from Briggs & Stratton and Toro, and will fit on over 150 different engine models in lawn mowers from these brands. The intake gasket is made of durable composite material. It is also a good idea to replace gaskets when servicing the carburetor to ensure a proper seal after reassembly. Be sure to use the right tools to install this part so that it isn't damaged in the process.
