Description
Overview:
The Taper Needle Spring is a genuine Villiers component for classic Villiers carburettors, specifically the 3/4 Junior and Lightweight types. It is a small helical steel spring that applies consistent tension to the taper (mixture) needle, helping the carburettor meter fuel accurately across the rev range. Correct needle tension supports stable idling, clean pick-up, and reliable running on vintage garden and construction machinery powered by Villiers engines. Supplied as unused old stock, it may show light tarnishing or age-related marks from storage, but remains fully functional. OEM No. V107X7 provides an easy reference when matching parts during servicing or restoration work.
