Kawasaki 39129-2116 Governor Spring

Product Description

The KAWASAKI 39129-2116 is a governor spring used in Kawasaki small engines to maintain proper engine speed under varying load conditions. The governor spring connects to the governor arm and throttle linkage, applying tension that works against the centrifugal governor to hold a target RPM. When the spring loses tension, stretches, or breaks, the engine may surge, hunt, or fail to hold a steady speed. Replacement by a qualified small engine technician restores correct governor response and engine stability.

This governor spring is intended for use in Kawasaki-powered lawn and garden equipment. Typical applications include walk-behind mowers, riding mowers, and other outdoor power equipment fitted with Kawasaki single- or twin-cylinder gasoline engines. Installation is performed during governor linkage service, carburetor adjustment procedures, or as part of an engine surging diagnosis.

Key Features

• OEM Kawasaki governor spring engineered to factory tension specifications
• Restores proper engine speed regulation and eliminates RPM surging or hunting
• Direct replacement design for straightforward installation without modification
• Compatible with Kawasaki lawn and garden engine applications

Compatibility

Designed as an OEM-style replacement governor spring for Kawasaki small engines used in lawn and garden equipment. Verify fitment against the engine model and serial number before installation.

Installation Notes

Governor spring replacement is typically performed by a qualified small engine technician. Shut off the engine and allow it to cool completely before beginning any service work. Use needle-nose pliers to carefully remove and reinstall the spring on the governor arm and throttle linkage posts, taking care not to bend or distort the linkage. After installation, verify engine speed and governor response before returning the equipment to service.
