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
