Engine Governor Control
The Kawasaki 39129-0042 Governor Spring is part of the engine's mechanical governor and throttle-control system.
The governor system responds to changes in engine load and helps regulate engine speed. The spring provides tension to the connected governor linkage, allowing the governor system to operate through its intended range.
A stretched, damaged, incorrect, or missing governor spring can affect the operation of the throttle and governor system.
Replacing it with the correct Kawasaki OEM governor spring helps restore the engine's original control-system configuration.

Broken

Damaged

Turn off the engine and remove the ignition key.
