Description
Overview:
The Air Regulating Screw is a genuine Villiers part for the Zenith 24 T-2 carburettor, designed to control the air passage and fine‐tune the air‐fuel mixture. Made from durable, corrosion‐resistant machined brass with a slotted head and tapered tip, it delivers precise, repeatable adjustment for smooth running. This screw is suitable for classic garden and construction machinery fitted with Zenith 24 T-2 or 24T-2 carburettors. Supplied as unused old stock, it retains original build quality and may show light tarnish typical of vintage parts. Correct air regulation helps reduce hesitation, improve idle stability, and optimise throttle response, making this part useful for both routine servicing and sympathetic restoration where maintaining authenticity matters. Genuine Part, OEM No. 09845.
