BRIGGS & STRATTON 692786 Engine Ring Set Oversized 20"

The Briggs & Stratton 692786 Engine Ring Set Oversized 20" is a piston set designed for use as a replacement to assist in ensuring proper compression in compatible small engines. It is mainly used to provide a controlled clearance between the piston and cylinder wall to minimize combustion gas leakage and facilitate oil control. The oversized design allows to compensate for cylinder damage by creating a tighter fit while in use. That assist in holding combustion pressure in the cylinder and controlling lubrication. This is required to maintain stable engine performance, retain compression, minimize oil consumption and ensure consistent operating efficiency.
