Description
Overview:
This Piston Ring +020 is a durable metal ring for Villiers 150 cc two-stroke engines, used to restore and maintain proper cylinder sealing. The "+020" size denotes an oversize of 0.020 inch (0.51 mm), intended for use after a cylinder re-bore to the matching repair size. By sealing the combustion chamber, it helps maintain compression, reduce blow‐by, and support reliable starting and smoother running. It is suitable for engine rebuilds, servicing, and long-term maintenance of older machinery powered by Villiers 150 cc units. Supplied as unused vintage old stock, the ring may show light tarnishing or storage marks that do not affect function. A practical choice for restorers and technicians who need an accurate, service-ready compression ring to bring performance back within specification.

Typical Applications:
