Replacement carburetor rotor for O.S. Engine OS29183210

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 is part of the throttle and venturi assembly and influences airflow at varying throttle positions. After fitting a new rotor, recheck idle and high-speed needle settings and confirm throttle linkage geometry to recover predictable engine response during tuning sessions.

Avoid forcing components to protect the shaft and body.

Compatibility and inspection: this item is described by its O.S. Engine part code OS29183210, verify the rotor profile and locating details on your carburettor before installation and perform a bench check of throttle movement and needle adjustments after fitting.
