Description
Overview:
This Injection Valve is the genuine Stihl fuel injector for TS480i and TS500i disc cutters, supplied to OEM specification under number 4250 130 3311. It meters petrol precisely into the engine's intake, supporting reliable starting, clean idling and strong performance under load. The assembly features a precision metal body with durable, fuel‐resistant seals and a moulded electrical connector for a secure fit. Built to cope with dust, vibration and heat found on site, it helps keep electronically controlled two‐stroke engines running as intended. If your cutter is hard to start, bogs under throttle or uses more fuel than normal, a worn or blocked injector is a common cause. This genuine part restores correct fuel delivery on Stihl TS480i and TS500i machines.
Key Features:
- Genuine Stihl part for assured compatibility and reliability (OEM 4250 130 3311).
- Accurate fuel metering to maintain easy starting, stable idle and crisp throttle response.
- Robust metal construction with fuel‐resistant O‐rings to withstand site conditions.
- Calibrated to the TS480i/TS500i injection system for consistent engine behaviour.
- Direct‐fit replacement with plug‐in connector and O‐ring seating; no modifications required.
- Helps recover cutting performance and power under heavy load.
- Supports efficient fuel use and reduces symptoms of rich/lean running caused by injector wear.
- Engineered to resist vibration, dust ingress and temperature cycles typical of concrete cutting.
- Compact form factor for easy access and straightforward installation during routine servicing.
- Reduces downtime by restoring correct fuel delivery without complex adjustments.
Typical Applications:
Used during maintenance or repair of Stihl cut-off saws that show hard starting, uneven idle, hesitation or loss of power due to injector blockage or wear. Suitable for machines used on construction sites, utilities and landscaping for cutting concrete, masonry, blocks and asphalt, where consistent performance and reliable fuel delivery are essential.
