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 genuine OEM gasket sits between the carburetor and cylinder to create a seal on a wide range of different lawn mower engines. The carburetor is responsible for mixing fuel and air, so it is important that it remains well sealed. The cylinder sits on top of the combustion chamber, and must also be sealed to provide the proper amount of pressure to drive the pistons. Therefore, it's crucial that nothing escapes from the engine where these two parts meet. Gaskets are designed to take a lot of wear and tear, but they can eventually blow after repeated exposure to heat and pressure. When a carburetor and cylinder gasket blows, the engine will not perform as well. Look out for vibrations, backfiring, low output, or an engine that stops shortly after startup. To replace this gasket, use a screwdriver, wrench set, and pliers to gain access to the carburetor's inner workings. This part is compatible with Toro, Lawn Boy, and Briggs & Stratton lawn mowers and comes sourced from its original manufacturer. This part ships individually.

Secures components like gas tanks on small engines. Replace if stripped, damaged, or lost. Flange design distributes clamping force evenly. Verify fit.

Engine gaskets are designed to seal and insulate various parts of the engine. Because they are subject to high heat and constant pressure, they can wear down and degrade over time. This can affect the seal of the engine and ultimately inhibit performance. If gaskets are left in disrepair, it can even create bigger problems in the engine. Therefore, a full replacement will be necessary. Gasket maintenance and replacement are considered parts of routine maintenance for lawn equipment. There are several of these gaskets found on lawn and garden equipment engines, and when more than one is faulty, it may be best to replace the entire set. This genuine set can be the perfect solution for compatible engines. This genuine OEM engine gasket set is designed to exact manufacturer standards and comes from Briggs & Stratton. This kit is designed for use with generator and lawn mower engines on select units from Toro and Briggs & Stratton. There are more than 150 units that can take this gasket set.

This exhaust gasket is a genuine Midwest Engine replacement part for appliances operated by small engines, such as chipper shredders, snowblowers, leaf blowers, and lawn mowers. An exhaust gasket's purpose in the engine is to create a sealed layer between the carburetor and the exhaust tube to keep dirt and debris out of the infrastructure of the engine. A malfunctioning or broken exhaust gasket could compromise the seal between the carburetor and the exhaust tube, meaning that dirt and debris could get into the engine and cause damage. An exhaust gasket could be subject to damage from overuse and is generally known to require replacement over time from general wear and tear. If the exhaust gasket seal is compromised, it should be replaced immediately. Evidence of dirt and debris compromising an engine could take the form of oil leaking from the carburetor, black smoke pluming from the exhaust tube, and lower engine pressure than usual. This exhaust gasket is compatible with the following brands: Briggs and Stratton, Cub Cadet, and Toro. This part sold individually.
