This part is a breather gasket. This specific breather gasket is manufactured for use with small engines. The breather gasket forms a seal between the breather and the cylinder. The breather itself relieves the pressure that is inside of the crankcase by allowing the air to exit but not allowing the air to enter. A new breather gasket may be needed if the breather itself seems to be clogged. It can sometimes become clogged with oil. It's recommended to replace the breather gasket any time the breather itself is serviced to ensure that a proper seal is maintained. This part is a genuine Midwest Engine part and is an OEM part sourced directly from the manufacturer and it is sold individually. This specific breather gasket is compatible with engines, lawnmowers, and generators that are manufactured by Midwest Engine, Briggs and Stratton, Toro, and Lawn Boy.

This screw is a genuine Midwest Engine replacement part for small engine appliances, including lawn tractors, lawn mowers, snowblowers, leaf blowers, vacuums, and tillers. The purpose of a screw is to tightly link materials together through rotation that pierces into the material. A screw might have to be replaced in the event that it is lost or misplaced, a common occurrence due to its size. A screw might also be replaced if it deteriorates over time, through erosion, cracking, or piercing, thereby reducing its efficacy in holding materials together. This kind of damage can be attributed to general overuse, to age, or simply to long-term exposure. If a screw is subject to any of this kind of damage, it is best to replace it immediately, as the materials held together by the screw must continue to be held together. Remember to always wear gloves when handling, repairing, and operating outdoor equipment. This screw is compatible with the following brands: Briggs & Stratton, Toro, Cub Cadet, and Lawn Boy.

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.

This is a replacement screw that can be used on various types of lawn and garden equipment. The type of equipment will affect where the screw is used on the tool. A screw is used to attach various components together so nothing comes loose while the tool is in use. It can also be used with a nut. It's best to choose a nut that has the same finish and threading as the screw.A screw can be damaged in many ways. If this occurs, it will need to be replaced. Corrosion, wear and tear, extreme stress, and high temperatures can all cause a screw to fail. Inspecting the screw can indicate whether it will need to be replaced. Use a screwdriver to take off the old screw, or use a pair of pliers if the screw has become stripped. Replace it with a new screw.This is an authentic OEM replacement part sourced directly from the manufacturer. Each screw is sold individually. The component is designed for use with lawn mowers, snowblowers, tillers, pressure washers, leaf blowers, edgers, chainsaws, generators, and wood chippers manufactured by Briggs & Stratton, Simplicity, Toro, MTD, Cub Cadet, Lawn-Boy, Homelite, and Murray.

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 replacement friction spring is a genuine OEM part meant for any number of small appliance engines run using a starter rope. This spring absorbs large amounts of kinetic energy that could damage the starter rope pulley system. It helps keep the pulley from being overstretched, which would create enough pressure to break the entire system. This spring sits at the center of the pulley system and creates resistance as the user yanks the starter rope. Friction springs can become worn out after repeated use, especially if a user tends to yank the starter rope quite forcefully. The most obvious sign of a worn of friction spring is if the pulley system lacks any resistance. As the user pulls the cord, they should feel a little pull back, but if the friction spring is worn, there will be much less resistance. Replacing this part is straightforward and will only require a screwdriver. Simply open the pulley system, carefully remove the old spring, and install the new one. This part is compatible with a wide number of appliances from Toro, Vanguard, Briggs & Stratton, and Lawnboy. It comes sourced from the original manufacturer and ships individually.
