Description
Overview:
This genuine Villiers valve is a precision replacement part for Villiers MK12 and C12 small petrol engines. Made from durable metal with accurately finished sealing faces, it controls gas flow within the cylinder and seals against the valve seat to maintain compression, helping the engine start reliably and run smoothly. As unused old stock, it is an authentic OEM component that matches original specifications for fit and function. It is suitable for routine maintenance or full rebuilds of vintage Villiers engines used on garden and light construction equipment. The part may show minor storage tarnish typical of vintage stock, which does not affect performance. Designed as a direct-fit swap, it supports long service life when installed with correct clearances and a properly lapped seat.
