Description
Overview:
The Low Speed Adjustment Screw (part no. 1120 122 6801) is a genuine Stihl component for setting the low‐speed circuit on the carburettor of selected Stihl machines, including the FS220 and FS220K. This precision‐machined metal screw allows fine control of mixture at idle and during initial throttle opening, helping to achieve a steady tickover and smooth pick‐up from idle. Built to Stihl's OEM specification, it fits directly into the carburettor body used on the compatible models listed below. It is suitable for routine maintenance or repair when the original screw is worn, damaged, or missing. Robust threads and a shaped head enable accurate adjustment using the correct tool, making it a reliable choice for both tradespeople and home users.
Key Features:
- Genuine Stihl OEM part for assured fit, function, and durability
- Precision threads for accurate low‐speed mixture setting
- Helps maintain stable idle and clean throttle response
- Direct replacement; no modification required on listed models
- Designed to resist vibration and hold settings securely
- Straightforward installation using the correct carburettor adjusting tool
- Supports reliable running when tuning after servicing or seasonal changes
- Suitable for both professional workshop use and DIY maintenance
Typical Applications:
Used during servicing and tuning of Stihl two‐stroke machines to set the low‐speed mixture after carburettor cleaning, diaphragm replacement, or air‐filter changes. Ideal for restoring a steady idle, improving pick‐up from low rpm, and correcting stalling or hesitation following vibration or wear that has affected the original adjustment screw.
