O.S. Engine OS25881100 Carburettor Body for Nitro RC 40L 55HZ  [OS25881100]

Spare carburettor body for scale nitro cars

This O.S. Engine carburettor body is offered as a replacement part for nitro-powered model engine carburettor assemblies. The product is referenced by size/code 40L 55HZ and model number OS25881100 to assist hobbyists in identifying the correct spare for repairs or rebuilds.

The part serves as the carburettor housing that interfaces with throttle linkages and the jets, so it has a direct effect on fuel delivery, idle consistency and mid-range throttle response. It is supplied as a single spare component rather than as a complete carburettor set.

Fitting typically involves removing the carburettor top and correctly seating gaskets and the needle; retain your original jets and needle settings as a baseline and check for air leaks after refit. After changing the body, re-check idle mixture and throttle transition since airflow and tuning balance can be affected.

Use this spare when the original carburettor body is damaged or beyond service, or when you need a like-for-like replacement to retain tuning control and dependable running in nitro RC models.
