Description
Overview:
This Speed Regulating Screw is a genuine Villiers spare engineered for accurate engine speed adjustment on industrial applications using the Dellorto FHC20-16A carburettor. Precision‐machined from durable steel, it provides stable and repeatable adjustment so your engine holds a consistent idle and governed running speed under load. Built to the original specification (OEM No. 32578), it is a direct replacement for worn or damaged screws and is suitable for vintage Villiers engines, including the C30 and C30/2. Its robust construction withstands the vibration and heat of industrial duty, helping to keep older engines reliable and easy to tune. Use it during servicing, restoration, or carburettor overhaul to restore proper control over engine speed and ensure smooth, efficient operation.
