Description
Overview:
The Governor Gear Sleeve is a genuine Villiers part for classic petrol engines, supplied under MPN EM129/1. It is a durable metal sleeve that supports and guides the governor gear, helping to maintain steady engine speed and smooth throttle response. This part is suitable for small stationary engines used in compact machinery, including the Villiers MK10 and MK12 ranges. It is ideal for replacing a worn or damaged sleeve during routine maintenance or a full rebuild. As unused old stock, it is an original vintage component and may show light cosmetic signs of age from storage. Correct governor operation reduces hunting and surging, protecting the engine and improving running quality across typical site and garden equipment.
