Description
Overview:
Jet Needle No. 5 is a genuine Villiers replacement part for the carburettor on selected 2‐stroke engines, including the 249CC and MK25A. Made from precision‐machined brass, it meters fuel against the needle jet to control the fuel-air mixture across the throttle range, supporting smooth running, clean pick‐up, and stable idle. It is identified by OEM No. V137X10 for straightforward selection during servicing and restoration. Built to handle the heat and vibration typical of older plant and garden machinery, this needle is well suited to maintaining original performance on vintage Villiers engines. Supplied as unused old stock, it may show light cosmetic tarnishing from storage, which does not affect function. A dependable choice when accuracy and authenticity matter in rebuilds and routine maintenance.
