Main Jet Cap for Villiers B1320 Carburettor C25 C28 C30 C45 Engine – 26466

Description

This Genuine Villiers Main Jet Cap is a precision brass plug for the B1320 carburettor used on classic Villiers petrol engines, including the C25 and C28. It threads into the main jet gallery to seal the fuel passage and protect the metering jet from dirt and damage. The robust brass body resists corrosion in petrol environments and provides a long service life. A hehead makes removal and refitting straightforward during servicing. Supplied as unused vintage stock, the part may show light tarnishing that does not affect performance. Fitted correctly, it helps maintain stable fuel mixture, smoother running, and reliable starting across a range of small machinery powered by Villiers engines. Genuine status ensures correct fit and compatibility with original B1320 carburettor components.
