Description
Overview:
This throttle spring is a small but critical part for Loncin petrol engines, helping the throttle and governor hold a steady engine speed under load and at idle. Made from hardened spring steel for resilience, it connects the throttle/governor linkage and provides the return force needed for accurate speed control. It is suitable for a range of Loncin engines, including G240F and G270F variants, and corresponds to MPN 171610001-0001. Use it to restore correct response where throttle action has become weak, hunting, or inconsistent due to a fatigued or stretched spring. Typical applications include generators, plate compactors, pumps, and other machinery powered by Loncin single-cylinder engines. Built for dependable performance in vibration-prone environments, it helps maintain smooth running and efficient fuel use.
Key Features:
- Helps maintain stable governed speed and smooth throttle response under changing loads
- Durable spring steel construction for long service life in demanding conditions
- Correct hook ends and length to suit Loncin linkages for a reliable fit
- Resists fatigue from vibration, heat cycles, and frequent throttle movement
- Supports clean idle, reduces surging, and improves overall drivability
- Straightforward replacement with basic hand tools and no special setup
- Matches Loncin reference 171610001-0001 for accurate identification
- Suitable for general maintenance or preventative replacement to avoid downtime
Typical Applications:
Used on Loncin-powered equipment such as site generators, plate compactors, pressure washers, water pumps, tillers, and other machinery where steady engine speed is essential. Ideal for repairs when the original spring is stretched, corroded, or broken, and for restoring consistent speed control and safe shutdown behaviour.
Also known as:
Throttle return spring, governor spring, governor control spring, throttle linkage spring, speed control spring, carburettor return spring for throttle/governor arm.
