Description
Overview:
This genuine Villiers Throttle Stop Screw (V1331E) is a small but critical carburettor component for vintage engines, including the C12 and B10/1. Machined from durable metal, it sets the resting position of the throttle plate to control idle speed, helping the engine start reliably and run smoothly without stalling. As unused old stock, it preserves the original specification and fit required for faithful restorations and dependable maintenance. The screw provides fine, repeatable adjustment so you can dial in a steady idle and prevent the throttle from closing too far. It is suitable for workshop servicing or as a direct replacement for a missing or worn part on period Villiers-powered machinery. Expect minor storage tarnish only; performance is unaffected.
