O.S. Engine OS27915000 Carburettor Rubber Gasket 60B  [OS27915000]

Replacement carburettor gasket 60B

This O.S. Engine OS27915000 carburettor rubber gasket 60B is an RC-scale replacement sealing part for carburettors, designed to restore or maintain the carburettor's seal where rubber gaskets are required.

Functionally the gasket provides an air- and fuel-resistant seal between mating surfaces in a carburettor assembly, helping to stabilise idle and preserve consistent fuel/air mixture during adjustment. As a simple consumable part, it is intended for routine replacement when the original gasket shows wear, cracks, or loss of elasticity.

Installation notes: ensure mating surfaces are clean and free of old gasket material or residue before seating the gasket, align the gasket carefully to avoid pinching, and tighten carburettor screws evenly to the manufacturer's recommended torque to avoid deformation. After installation, verify idle and mixture settings on the engine and check for any signs of leaks during a short run.

Maintenance tip: inspect gaskets whenever the carburettor is removed for cleaning or tuning, and replace immediately if the rubber appears hardened or compressed to prevent air leaks that affect mixture consistency.
