Description
Overview:
These genuine Throttle Stop Screws are OEM replacements for the Villiers B1016 carburettor used on 125cc and 150cc four-stroke vertical shaft industrial engines (commonly Type 512V and 515V). Manufactured to original Villiers specifications under OEM No. 22422, the screws are precision-made steel components that set the throttle closed position and stabilise idle speed. Correct adjustment prevents excessive idle, stalling, and uneven running, helping the engine deliver reliable performance under load. Supplied as unused old stock, the parts may show light tarnishing or storage marks but remain fully serviceable. Suitable for maintenance and restoration of older machines where maintaining originality and fit is important, these screws are a straightforward, direct-fit solution for the B1016 carburettor found on many vintage Villiers-powered tools and plant.
