Description
Overview:
The B10/1 Carb Replacement Main Jet No 28 (OEM 25918) is a genuine Villiers main jet for restoring correct fuel metering in classic Villiers carburettors. Precision‐machined from durable brass, this threaded jet meters fuel through the main circuit to maintain a stable air‐fuel mixture at working speeds. It is designed for use in B10/1 and B101 carburettors commonly found on vintage small engines used in mowers, rotavators, generators and other plant. As unused old stock, the part may show light tarnishing from storage, which does not affect function. Replacing a worn, blocked or incorrect jet with the correct No. 28 size helps resolve rich/lean running, poor throttle response and excessive fuel use, keeping classic machinery operating reliably.
