Description
Overview:
The Pilot Screw for Amal Carburettor (OEM No. 519/015) is a genuine Amal adjustment screw used to fine‐tune the idle and low‐speed air‐fuel mixture. Made from durable brass, it resists corrosion and provides precise, repeatable adjustment. This small threaded screw features a slotted head for screwdriver use and a finely tapered tip to deliver accurate mixture control. It is a direct replacement for worn or damaged screws in Amal carburettors fitted to small petrol engines commonly found in construction and garden machinery, as well as stationary engines.
