Replacement Carburettor Gasket for GT15HZ OS49415000 - O.S. Engine  [OS49415000]

Sealing role and workshop fitting steps

The OS49415000 carburettor gasket from O.S. Engine serves as a direct replacement part for the GT15HZ carburettor. It provides the sealing surface between sections of the carburettor to preserve accurate fuel and air metering in glow engine configurations.

Its sole purpose is mechanical sealing: keeping mating faces tight, preventing leaks, and supporting stable needle and throttle response. During inspection, replace gaskets that are flattened, torn, or otherwise compromised to reinstate a proper seal before any tuning work.

Fitting is manageable for those experienced with glow engines. Remove the carburettor, separate the relevant mating surfaces, clean away residue and remnants of the old gasket, and place the new part ensuring all cutouts and ports line up. Reassemble with even torque on screws to prevent body distortion that would jeopardize the seal.

Using a new gasket helps keep airflow and fuel pathways consistent, which makes needle adjustments more repeatable. After reassembly monitor for fuel odors, visible seepage, or idle instability, as these point to misalignment or damaged components that need further attention.
