O.S. Engine OS29183210 Carburetor Rotor replacement part for O.S. Engine carburettor assemblies  [OS29183210]

Carburetor rotor for O.S. Engine

This is an RC-scale carburetor rotor sold under the O.S. Engine designation OS29183210, presented as a replacement rotor for the carburettor models referenced in the part name. The rotor is intended for use in nitro/fuel RC engine carburettor assemblies as a service item during maintenance or tuning.

Role and tuning context: the rotor forms part of the throttle/venturi mechanism inside the carburettor and affects airflow behaviour at different throttle positions. When replacing the rotor, expect to verify idle and high-speed needle settings and confirm throttle linkage geometry to restore predictable engine response during tuning sessions.

Installation notes: remove the carburettor top following your engine's service procedure, slide the rotor onto the throttle shaft aligning any locating features, secure the retaining hardware and verify free rotation across the throttle travel. Use the original screws or retainers and avoid forcing the rotor to prevent damage to the shaft or body.

Compatibility and inspection: this item is described by its O.S. Engine part code OS29183210, inspect your carburettor assembly to confirm the rotor shape and locating features match before fitting, and perform a bench check of throttle movement and needle adjustments after installation.
