Description
Overview:
The Pilot Air Adjusting Screw is a small, precision-machined component for Villiers carburettors, used to set the pilot (idle) air mixture for smooth and reliable running. Made from robust brass for durability and resistance to corrosion, it replaces worn or damaged screws to restore accurate air control in the carburettor body. This part fits classic Villiers units such as the S22 and S24 found on many vintage engines used in garden and light construction equipment. It is an unused old stock item and may show age-related tarnish or minor surface marks, but remains fully functional. Supplied as a direct replacement for OEM No. V775, it is suitable for maintenance and restoration work where keeping original specifications matters.
Key Features:
- Direct replacement for OEM No. V775 for correct fit and function
- Brass construction resists corrosion and seizing in the carburettor body
