Description
Overview:
This genuine Villiers governor adjusting nut (OEM No. 86 75) is a small but critical component for the BSA 320CC and 420CC industrial engines. Made from durable metal with a precise threaded profile, it allows accurate setting of the governor mechanism so the engine holds a steady speed and responds predictably under changing loads. It helps prevent hunting, overspeeding, and poor idle by locking the governor linkage in the correct position. Supplied as unused old stock from period manufacture, the part may show storage tarnish or light cosmetic marks, but performance is unaffected. Ideal for maintenance, repair, and sympathetic restoration of vintage industrial plant using BSA engines, including static equipment and mobile machinery where reliable speed control is essential.
