Description
Overview:
The Honda Throttle Spring (16562-ZE3-000) is a genuine replacement spring for the throttle mechanism on Honda GX340 and GX390 petrol engines. Made from high-tensile steel, it provides a consistent return force to keep the throttle plate closing reliably and the engine settling to a steady idle. Correct spring tension helps deliver smooth response as load changes, aiding overall fuel efficiency and dependable running. The spring is precision-formed to fit the original linkage points on Honda small engines, making it suitable for equipment commonly found in construction, landscaping, and agriculture. Typical machines powered by GX340 or GX390 engines include generators, plate compactors, water pumps, pressure washers, mixers, and other site tools where accurate speed control and reliable throttle return are essential.
Key Features:
- Genuine Honda part (Genuine Part) for assured compatibility and performance
- OEM reference 16562-ZE3-000 matches the original specification
- Durable steel construction resists fatigue and deformation over repeated cycles
- Helps maintain stable idle and consistent throttle return for smooth operation
- Supports responsive acceleration and control under varying loads
- Precision end loops for a secure fit on factory throttle/linkage points
- Direct replacement with no modifications required; quick to fit with basic hand tools
- Suitable for routine maintenance to restore correct throttle feel on aging engines
- Designed for frequent start/stop duty typical of site and garden machinery
- Compatible with a wide range of GX340/GX390 model variants (see list below)
Typical Applications:
Replacement of a worn or weakened throttle return spring on equipment powered by Honda GX340 or GX390 engines. Common on site generators, pressure washers, water pumps, plate compactors, cement mixers, trowels, and larger garden or grounds-care machines. Helps address sluggish throttle return, inconsistent idle, or poor throttle response caused by loss of spring tension, bringing the engine back to predictable speed control during daily use.
Also known as:
Throttle return spring, throttle linkage spring, carburettor throttle spring, engine throttle spring. Often referred to simply as a throttle spring in parts lists and service manuals. These terms describe the same function: providing the return force that closes the throttle and stabilises engine speed after acceleration.
