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 valve spring is made for small engines and works on a range of different types of outdoor equipment. The valve spring plays an important role in internal combustion engines. A camshaft will open the valves, often using valve lifters. The spring is responsible for closing the lifters. Some of the symptoms of a broken valve spring include performance issues such as misfiring and loss of power, noise from the valve, and eventually internal damage to the machine's engine. Those who believe they have a damaged or broken valve spring should replace the spring as soon as possible. This will ensure the machine continues to run properly. This is a genuine OEM valve spring that is sold individually. The spring will work for many types of small engines including those found on lawn mowers, tillers, yard vacuums, and generators. Brands that can utilize the valve spring include Toro, Cub Cadet, MTD, Simplicity, Craftsman, Lawn-Boy, Murray, and Briggs & Stratton.

Replace a worn valve retainer if your engine has compression loss or valve train noise. This washer-shaped part secures the valve spring lock on the valve.

This is an authentic muffler deflector screw that is found in small engines for outdoor power equipment from Briggs & Stratton. This metal screw is designed to secure the muffler deflector to the flywheel. In select models, it may also be used to secure the starter clutch to the flywheel. The screw is durable but exposed to high heat and constant wear, which means that it can become damaged or worn with regular use. If the screw is lost or damaged, it will need to be replaced. It should always be replaced with a genuine OEM part. This OEM muffler deflector screw is manufactured by Briggs & Stratton to exact standards and is compatible with several models of small engines. It can be used with various models of blowers, pressure washers, generators, and snow throwers from Toro, Murray, and Briggs & Stratton. It is sold as an individual replacement part. To replace this screw, the flywheel cover will need to be removed. Then, if it is still present, the old screw will need to be removed and the new one can be installed. This screw requires a hex or Torx screwdriver to install. Always wear gloves and disconnect the spark plug for safety when performing engine repairs.

This is a small rubber grommet that connects the breather tube to the engine on a lawn mower.
