Description
Overview:
This engine spring is a precision-made component for Robin/Subaru small industrial engines, including DY23 and DY27. Manufactured from durable spring steel with a resilient finish, it delivers the controlled tension needed for smooth operation of engine linkages and assemblies. It helps maintain stable throttle response and reliable return action in everyday use, supporting consistent performance under vibration and load. Identified by OEM No. 243-35021-03, it is sized and formed to sit correctly within the engine's existing hardware without modification. Suitable for engines used across compact construction and garden machinery, it is a straightforward replacement during routine servicing or repairs where tired or stretched springs can lead to erratic running or poor idle stability.
Key Features:
- OEM reference 243-35021-03 for correct fit and function
- Spring steel construction for long service life under repeated flex
- Consistent tension to support smooth throttle and linkage movement
- Helps prevent hunting, uneven idle, and sluggish return in control systems
- Resistant to wear and fatigue in high-vibration environments
- Straightforward installation with basic hand tools
- Suitable for professional workshops and DIY maintenance
- Compatible with common engine-mounted linkages and brackets
- Supports efficient engine performance and reduces downtime
- Compact, lightweight form factor for easy handling and storage
Typical Applications:
Used within the engine assembly to provide return and control tension on linkages in Robin/Subaru DY-series units. Common in plate compactors, generators, pumps, light plant, and garden equipment powered by DY23 or DY27 engines. Ideal when refurbishing engines, correcting erratic throttle response, or replacing fatigued springs during scheduled maintenance.
