Description
Overview:
The Main and Needle Jet for Villiers S10/2 carburettors is a genuine Villiers OEM component (OEM No. 25774) designed to restore precise fuel metering in lightweight four-stroke engines. Precision-machined from brass for durability and corrosion resistance, it governs fuel flow through the main and needle circuits so the S10/2 carburettor delivers clean running, easy starting, and stable performance. Suitable for horizontal and vertical engines in 50 cc, 75 cc, and 125 cc capacities, it fits the needs of compact stationary and horticultural machinery. As a vintage service part, light tarnishing may be visible without affecting function or fit. Ideal for routine servicing or full restorations, it integrates neatly with Villiers S10/2 units found on models such as 505H and 507H.
