Description
Overview:
The Idle Speed Adjustment Screw is a genuine Stihl part designed for fine-tuning the idle (tick-over) speed of compatible 2‐stroke machines such as the KM100 and KM100R Kombi engines. It acts on the carburettor throttle stop to set a stable idle, helping the engine run smoothly without stalling between cuts or tasks. Built from robust, wear‐resistant materials, it is made for frequent adjustments and everyday workshop use. Correct idle adjustment improves starting, throttle pick‐up and overall reliability, reducing unnecessary clutch engagement at rest. If your machine hunts, stalls at idle, or the head/blade turns when it should not, replacing a worn or missing screw and setting the idle can restore proper operation. Stihl part number: 4140 122 6200.
Key Features:
- Genuine Stihl part for assured fit and performance
- Precise idle control for smooth, stable running
- Durable construction suited to regular servicing and adjustment
- Helps prevent unwanted head/blade movement at idle
- Supports easier starting and cleaner throttle response
- Simple to install with standard hand tools
- Compatible with a wide range of Stihl brushcutters, hedge trimmers, blowers, sprayers and Kombi engines
- Ideal replacement when the original screw is damaged, lost or stripped
Typical Applications:
Used during routine servicing or after carburettor work to set tick‐over on Stihl handheld machines. Suitable for workshop tune‐ups, field adjustments and restoring stable idle after fuel, cable or carburettor changes. Helps keep trimmers, hedge cutters, leaf blowers and Kombi engines safe and controllable when off‐throttle.
