O.S. Engine OS44982200 Carburettor Rotor 61P FSa-110-P Replacement for O.S. Carburettor Assemblies  [OS44982200]

O.S. Engine Carburettor Rotor Replacement

This O.S. Engine OS44982200 carburettor rotor is a replacement component for compatible O.S. carburettor assemblies. It restores the rotor element where wear has degraded throttle response or fuel delivery. The item is identified by model number OS44982200 and internal code 61P FSa-110-P.

Fitting the rotor is straightforward for hobbyists experienced in nitro RC engine service. Remove the carburettor from the model, follow the manufacturer's disassembly steps, note rotor orientation and indexing marks, install the new rotor, then reassemble and bench-test for smooth, free movement before refitting. Run a short controlled break-in and verify idle and throttle response after installation.

Used as a service item rather than a tuning control, the rotor helps maintain consistent fuel metering across the throttle range. After replacement, recheck needle valve and idle settings and perform incremental load tests to confirm predictable engine response. This part is intended for RC hobby use only and not for full-size engines.

Fit this rotor when servicing O.S. carburettor assemblies to restore consistent throttle action and always verify fit and function during post-install checks.
