O.S. Engine OS73301612 16mm Dust Cap Set (3 pcs) for Carburettor and Exhaust  [OS73301612]

Sealing caps for 16mm engine ports

This accessory pack contains three caps made to cover 16mm carburettor and exhaust apertures on model engines. The set is offered for maintenance, brief storage and to stop dust and debris reaching internal passages.

To fit, press each cap into the carburettor throat or exhaust port until it seats with a slight interference. They are intended purely as protective covers and must be removed before the engine is run; they do not influence tuning or performance.

Keep these caps handy for transporting models, bench servicing or routine maintenance to prevent contamination of the carburettor barrel and exhaust runner. The three-piece quantity provides coverage for multiple outlets or a spare cap for convenience.
