Description
Overview:
This genuine Kohler governor spring (OEM No. 18 089 19-S) is a small, durable spring-steel component that controls engine speed by maintaining correct tension in the governor and throttle linkage. It keeps revs steady under changing loads, improves throttle response, and limits maximum RPM to factory settings. Designed for Kohler CH245 and SH270 engines used across compact construction and garden equipment, it replaces a worn or stretched spring to restore smooth, reliable running. The formed ends suit the original linkage for a straightforward swap with no modification. Built to Kohler's specifications, it offers consistent performance and long service life, making it a sensible maintenance item when addressing hunting, surging, or unstable idle on petrol-powered machinery.
