Description
Overview:
This High Speed Adjustment Screw is a genuine Stihl component for setting the carburettor's high‐speed mixture on selected Stihl machines, including the TS350AVE and TS360. Precision‐machined from brass with a slotted head and fine thread, it allows accurate control of maximum engine speed and fuelling under load. Correct adjustment helps maintain cutting performance, throttle response, and engine protection during demanding work. As an OEM part (MPN: 1108 122 6700), it is built to the exact specification required for the intended carburettors found on Stihl cut‐off saws and certain older Stihl chainsaws. Ideal as a direct replacement for a worn, seized, or missing screw, it restores proper tuning capability during routine servicing or after other fuel‐system work.
Key Features:
- Genuine Stihl OEM part for assured fit, function, and material quality
- Precision brass construction resists corrosion and galling in fuel environments
- Fine thread and slotted head give smooth, repeatable adjustment with a standard screwdriver
- Calibrates the high‐speed circuit to help achieve correct maximum revs and clean power delivery
- Helps prevent lean running at high speed, supporting engine longevity
- Correct geometry and thread pitch for the specified Stihl carburettors
- Suitable for routine servicing, carb rebuilds, or replacing a damaged adjuster
- Straightforward installation with no modification required
- Compatible with a range of Stihl cut‐off saws and selected classic chainsaws
- Direct reference to MPN 1108 122 6700 for easy identification
Typical Applications:
Used to fine‐tune the high‐speed mixture after carburettor cleaning or overhaul, when replacing fuel lines or filters, or to compensate for changes in temperature, altitude, or load. Common in workshop servicing of Stihl cut‐off saws and vintage chainsaws to restore strong top‐end power, stable operation at full throttle, and reliable performance during masonry, metal cutting, or timber work.
