Description
Overview:
The Governor Spring - Robin Part - RB230 42502 01 is a small, high-tension steel spring used to regulate engine speed on Robin (Subaru) small petrol engines found in construction and garden machinery. Fitted between the governor linkage and throttle mechanism, it helps the engine maintain a stable RPM as load changes, improving control, efficiency, and protection against over-revving. Built from durable spring steel for consistent elasticity and long service life, it provides a reliable replacement when the original spring has stretched, corroded, or broken. Suitable for equipment such as plate compactors, generators, water pumps, lawn mowers, tillers, and similar tools, it supports smooth running, dependable idle, and responsive throttle behaviour during regular use and maintenance.
