Parts for Briggs & Stratton 422437-1898-E1: Carburetor Assemblies Parts

A needle and seat kit is used similarly to a float valve. It allows fuel into the carburetor chamber when it is empty and stops more fuel from entering the same chamber when it is already full. With regular use and age, the needle and seat kit or valve will wear out, become damaged, or stop working efficiently. Signs of this include an engine that continuously revs and will not idle or one that won't start at all. To improve performance and prevent further damages, a new needle and seal kit must be installed.Installing a needle and seat kit is simple with the proper tools. Wear gloves for protection. Remove the damaged or worn needle and seal kit, clean the area, and replace it with a genuine OEM replacement part. Test the device before putting it back to use.This needle and seat kit is an authentic OEM part. It is supplied by the original manufacturer and sold individually. It is comprised of high-quality, durable materials. The needle and seat kit is compatible with Toro and Briggs and Stratton brands. The kit can be used with a variety of machines, including lawnmowers, generators, lawn tractors, snowblowers, and other devices with small engines.
