Description
Overview:
This throttle spindle is a genuine Zenith component for the Zenith 24T series carburettor used on classic JAP and Villiers engines. It is a precision‐machined metal shaft that supports and drives the throttle butterfly, helping to maintain correct alignment, minimise air leaks, and deliver smooth throttle response and stable idle. Supplied as OEM No. 012628, it is made for accurate fit and consistent operation in the Zenith 24T and related variants found on vintage stationary engines and small plant. Ideal for restorations or routine servicing on engines such as the JAP 4 and Villiers MK25, this is unused old stock and may show age‐related tarnish or storage marks without affecting function. A practical, authentic replacement for keeping period machinery running properly.
