Description
Overview:
The Governor Spring - Robin Part - RB261 42501 13 is a metal spring used in the mechanical governor system of Robin small petrol engines fitted to construction and garden machinery. It connects the governor arm to the throttle linkage to keep engine speed stable as load changes. Built for repeated flexing and vibration, it helps prevent hunting and overspeed, keeping output smooth on equipment such as generators, water pumps, plate compactors, and cement mixers. Ideal for maintenance or repair when speed regulation becomes erratic due to a worn or stretched spring, it restores proper governor response and consistent idle-to-full-throttle control. A practical, like-for-like replacement, it supports reliable operation in tough site and outdoor conditions.
Key Features:
- Durable metal construction designed for long service life in demanding environments
- Maintains consistent engine RPM under varying loads for smoother operation
- Helps cure symptoms such as hunting, surging, or overspeeding
- Correct rate and geometry for the governor linkage on applicable Robin engines
- Compact coil form with hooked ends for straightforward fitting and removal
- Suitable for preventative maintenance; replace when stretched, weakened, or corroded
- Supports efficient running and reduced wear by keeping speed within specification
- Stable performance across typical site temperatures and vibration levels
- Simple, cost-effective part to restore reliable throttle and governor control
Typical Applications:
Used on small petrol engines powering site and garden equipment where steady speed is important, including generators, pressure washers, water pumps, compressors, plate compactors, cement mixers, chippers, rotavators, and lawnmowers. Suitable for routine servicing or when diagnosing unstable RPM, poor load response, or erratic idle. A practical replacement during carburettor and linkage overhauls.
Also known as:
Engine speed governor spring, governor control spring, throttle governor return spring, governor tension spring, RPM control spring, speed regulator spring, governor linkage spring.
