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.
Seals between air cleaner and carburetor on small engines. Replace if torn, compressed, or causing air leaks that affect performance. Verify fit.
This set of authentic OEM replacement parts includes all of the gaskets needed to tune up a small lawn appliance engine. Gaskets are used anywhere that two parts meet in an engine. They serve as a seal, helping to prevent gases or liquids from leaking out of the engine. As they seal off different parts of an engine, gaskets are often exposed to a lot of heat and pressure. Over time, they can warp or be crushed under that pressure. The symptoms of a blown gasket will depend largely on which gasket is damaged. The difficulty of a repair will also depend on which gasket is damaged. If tuning up and replacing all gaskets, be prepared to disassemble a majority of the engine. This set of gaskets includes 12 different gaskets as well as five seals. This set is compatible with Toro and Briggs & Stratton lawn appliances. This set of gaskets is sourced directly from its original manufacturer and does not include any additional hardware.
O-ring seal for lawn and garden engines. Replace when worn, cracked, or leaking to prevent oil and fuel leaks. Verify fit with your engine model number.
