Description
Overview:
The Carburettor C1Q-S161 is a Genuine Stihl replacement part for selected two‐stroke brushcutters and augers, including the FS300 and FS350. Built around a compact, die‐cast alloy body with hard‐wearing components, it meters fuel and air precisely to keep your engine starting reliably, idling steadily, and pulling cleanly under load. Correct carburetion protects the engine from running lean or rich, supporting performance and service life in demanding conditions. This OEM unit is engineered to match the original factory specification for porting, fuel circuits, and linkage geometry, so it aligns with existing mounts and controls on compatible Stihl machines. It is a straightforward like‐for‐like replacement for worn or damaged carbs where tuning no longer restores stable operation.
Key Features:
- Genuine Stihl OEM part (C1Q-S161), MPN 4134 120 0652 for assured compatibility and fit
- Robust die‐cast alloy construction for durability in professional use
- Precise fuel‐air metering to improve starting, throttle response, and idle stability

- Stable performance across varied loads and ambient conditions
- Suitable for regular maintenance to restore efficiency and reduce fuel waste

- Built to withstand vibration, dust ingress, and routine cleaning
Typical Applications:
Used to restore reliable fuel delivery and engine stability on compatible Stihl brushcutters and earth augers. Ideal for professional landscaping, grounds maintenance, agriculture, forestry edges, and construction site work where consistent cutting torque and clean acceleration are required for clearing grass, brush, and saplings or drilling post holes.
