Description

Overview:
The rod spring for Robin/Subaru EC13V engines is a compact but important metal spring used in the control/linkage system to maintain correct tension and return action. Made from durable spring steel, it helps keep throttle and governor settings stable so the engine runs smoothly under varying loads. Supplied as a direct replacement for OEM No. 157-42803-03, it fits EC13 and EC13V petrol engines commonly used in compact construction and garden machinery, including plate compactors, generators, pumps and mixers. Ideal for routine maintenance or repair when the original spring is stretched, corroded or missing, this part restores reliable starting, steady idle and consistent running. It is designed for straightforward fitting with standard hand tools and no modification on EC13-series engines.

Key Features:
- Direct replacement for OEM No. 157-42803-03 for accurate fit and function
- Robust spring-steel construction for long service life under vibration and heat
- Helps maintain stable throttle/governor control to prevent surging or hunting
- Suitable for demanding site and outdoor use in construction and garden machinery
- Compact design shaped for EC13-series linkage geometry
- Easy to install with basic tools; no special setup typically required
- Restores correct return tension when the original spring is worn or lost
- Supports smooth idle, responsive acceleration and consistent top speed

Typical Applications:
Used during engine servicing and repairs on Robin/Subaru EC13-series equipment. Common when refurbishing throttle or governor linkages, after carburettor cleaning, or when a fatigued spring causes erratic idle or speed control. Suitable for site machinery such as compactors, cement mixers, pumps and portable generators, as well as garden equipment powered by EC13/EC13V engines.

Governor spring, throttle return spring, throttle/linkage spring, control rod spring, engine return spring, tension spring for EC13 series, Subaru EC13V control spring.
