O.S. Engine OS73301612 Three-Piece 16mm Dust Cap Kit for Carburettor and Exhaust  [OS73301612]

16mm protective plugs for RC engine ports

This simple RC accessory comprises three plugs engineered to cover 16mm carburettor and exhaust openings on model engines. The set is supplied for routine maintenance, short-term storage and to shield internal passages from dust and debris.

To install, push each plug into the carburettor bore or exhaust socket until it seats with a slight interference fit. These items are protective only and must be removed prior to running the engine; they are not part of the tuning or performance system.

Keep this kit with your tools for transport, bench work, and servicing to avoid contamination of the carburettor barrel and exhaust runner. Three caps allow you to protect multiple outlets or retain a spare.
