Description
Overview:
The Choke Shutter for Stihl two‐stroke equipment is a genuine Stihl replacement part designed to control air intake during starting and warm‐up. Moulded from fuel‐resistant black polymer, it sits in the carburettor choke bore and closes or opens with the choke lever to provide the correct mixture for reliable ignition, smoother idle, and fewer stalls in cold conditions. Supplied to original specifications under OEM Part No. 4140 141 3801, it is a direct fit for selected Stihl handheld machines, including the HS 45 hedge trimmer and FC 55 edger. Replacing a worn or warped shutter restores proper choke function and helps protect the engine from hard starting, flooding, or lean running at start‐up. Genuine Stihl quality supports consistent performance and long service life.
Key Features:
- Genuine Stihl part for assured compatibility and reliable performance (OEM 4140 141 3801)
- Precision‐moulded, fuel‐ and oil‐resistant polymer for durability and stable operation
- Restores correct choke action for easier cold starts and steadier idle
- Direct replacement with OEM geometry for full‐close and full‐open positions
- Helps prevent hard starting, stalling, and mixture issues caused by a damaged shutter
- Smooth edges and accurate pivot point promote consistent sealing in the carburettor
- Resistant to petrol and ethanol blends used in two‐stroke fuel mixes
- Easy to fit during routine carburettor service with basic hand tools
- Suitable for a wide range of Stihl trimmers, hedge trimmers, edgers, Kombi engines, and MultiSystem units
- Supports engine longevity by ensuring correct enrichment during start‐up
Typical Applications:
Used during carburettor maintenance or rebuilds on Stihl handheld machines to replace a cracked, warped, or missing choke shutter. Ideal when tackling hard starting after storage, cold‐weather use, or erratic idle. Suitable for professional users and homeowners maintaining hedge trimmers, brushcutters, edgers, Kombi engines, and MultiSystem tools.
