OS29183210 Carburetor Rotor for O.S. Engine — replacement service part  [OS29183210]

Service rotor for O.S. Engine carburettors (OS29183210)

This RC carburetor rotor carries the O.S. Engine part code OS29183210 and is supplied as a replacement element for the referenced carburettor assemblies. It is intended for use in nitro/fuel RC engine carburettor systems as a maintenance or tuning service part.

Durability and performance context: the rotor forms a core element of the throttle/venturi arrangement and affects airflow patterns across the throttle range. Inspect the rotor profile and seating to ensure consistent engine behaviour under load and during high-rev operation.

Installation notes: remove the carburettor top according to the engine service manual, align the rotor on the throttle shaft observing any locating tabs, secure using the original retainers and confirm unobstructed rotation through the full throttle arc. Do not force the rotor to avoid damage to the shaft or housing.

Compatibility and inspection: identified by O.S. Engine part number OS29183210, confirm the rotor shape matches your carburettor prior to fitting and carry out a bench check of throttle movement and needle adjustments after installation.
