Description

This genuine Briggs and Stratton idle mixture valve is an original OEM replacement part designed to fit select engines made by the brand. This valve is responsible for controlling the mixture of air and gasoline that enter the carburetor, which helps determine how much power gets to the engine. This valve opens and closes based on the pull of the engine throttle, allowing the engine to perform at the optimal level based on user need. The valve can wear out over time due to the constant repetitive motion and high heat exposure, which can result in the need for replacement. This part should always be replaced with a genuine OEM model. This OEM idle mixture valve is manufactured for use in lawn and garden equipment that features select small engines manufactured by Briggs and Stratton. It is sold as an individual unit and does not include any additional parts or hardware. If additional parts are needed, they will require a separate purchase. This part replacement should be done on an engine that has had sufficient time to cool so that there is no danger of burns. Gloves should be worn at all times and it may be necessary to drain some of the fuel before working on these engines.
