Description
Overview:
This Genuine Stihl choke shaft is a metal spindle that controls the choke position in the carburettor, helping set the correct air-fuel mix for reliable cold starting and smooth running. It is designed for Stihl lawn and garden power tools that share the 4180-series engine platform, such as the FC100 and FC110 lawn edgers, along with selected brushcutters, hedge trimmers, pole pruners and Kombi engines. As an OEM component, it fits precisely in the carburettor housing, transferring movement from the external choke control to the internal choke mechanism. Built to withstand vibration, fuel exposure and frequent use, it restores positive choke action when the original part is worn, bent or seized, and supports consistent performance and easy starting.
Key Features:
- Genuine Stihl OEM part for assured fit and function on specified models.
- Precisely machined metal shaft for accurate choke operation and throttle response.
- Durable construction resists wear, fuel, oil and vibration for long service life.
- Direct replacement for 4180 121 3000; no modifications required.
- Helps improve cold starts, warm-up, idle stability and overall running.
- Supports correct carburettor setup during servicing or rebuilds.
- Compact, robust design to maintain alignment and smooth rotation in the carb body.
- Suitable for professional and domestic users maintaining Stihl equipment.
Typical Applications:
Used during carburettor repairs or maintenance to replace a damaged or worn choke shaft that causes hard starting, flooding, or poor idle. Ideal when refurbishing edgers, brushcutters, hedge trimmers, pole pruners or Kombi units that show inconsistent choke action. Helps restore dependable cold starts and stable running after long service or storage.
