Description
Overview:
This genuine Honda governor spring keeps GX340 and GX390 petrol engines running at a steady, controlled speed under changing loads. Made from durable steel with a protective finish, the spring links the governor mechanism to the throttle to fine‐tune engine speed, stabilise idle, and hold the governed maximum RPM. It is engineered to the correct rate and length for Honda's GX340 and GX390 series, ensuring the governor responds quickly and accurately. Ideal for maintaining reliability in equipment powered by these engines, it helps reduce hunting and surging, supports fuel efficiency, and protects the engine from over‐revving. Supplied to Honda OEM specification under part number 16561-ZE3-000, this is a straight swap for worn or stretched springs during routine servicing or repair.
Key Features:
- Genuine Honda part for assured fit and performance on GX340 and GX390 engines
- Correct tension characteristics to maintain precise governed speed and stable idle
- Durable steel construction with corrosion-resistant finish for long service life
- Helps prevent hunting, surging, and over‐revving under variable loads
