Spring-valve 690520

This is genuine OEM sourced part and is specially designed for use with Briggs and Stratton engines commonly installed on lawn and garden equipment. It is an identical replacement for a missing or damaged spring that was originally installed on a new unit. The purpose of this hardware is to apply tension on the exhaust and intake valves. Make sure to refer to the owners manual and the appropriate diagrams of your model for the correct installation of this component. This high-quality spring is made of durable metal and is sold individually. To replace it, you will need to unscrew and remove the cylinder head. This will allow you to take out the valve and replace the spring.
