Description
Overview:
The Honda Spring Governor (MPN 16561-ZM1-000) is a Genuine Honda part used to control engine speed on selected Honda petrol lawnmowers. It is a compact coil spring made from durable spring steel with hooked ends, designed to link the governor arm to the carburettor/throttle linkage. By maintaining the correct governor tension, it keeps engine revs stable under changing load, reducing hunting and surging for a cleaner cut and efficient fuel use. Built for precise fit and reliable operation, it is suitable for models such as the HRB425 CQX and HRG415C1. Choosing the genuine component ensures correct length, coil rate and compatibility with the original linkage geometry, helping to protect engine performance and extend service life.
Key Features:
- Genuine Honda part for assured fit and performance on specified models
- Regulates governed engine speed to keep cutting performance consistent
- Durable spring steel construction for long service life
- Correct coil rate and hook profiles for reliable linkage engagement
- Helps prevent engine hunting, surging and stalling under load
- Supports smooth idle and stable running across cutting conditions
- Straightforward to install during routine service with basic tools
- Suitable replacement for worn, stretched or damaged original springs
Typical Applications:
Used on Honda walk-behind lawnmowers to restore and maintain stable engine speed during grass cutting, especially when load varies in thicker or damp grass. Ideal for resolving poor throttle response, unstable idle, or inconsistent blade speed caused by a fatigued or stretched governor spring. Commonly fitted during carburettor or linkage maintenance.
Also known as:
Governor tension spring, throttle governor spring, speed control spring, carburettor linkage spring, governor control spring, mower governor linkage spring.
