O.S. Engine OS29183210 Carburetor Rotor — tuning and service replacement  [OS29183210]

OS29183210 rotor — tuning-focused replacement for O.S. Engine

This rotor is marketed under the O.S. Engine part code OS29183210 and serves as a replacement rotor for the carburettor models listed in the part reference. It is intended for nitro/fuel RC engine carburettor assemblies where parts are replaced as part of tuning or maintenance.

Tuning impact: because the rotor helps shape the venturi and throttle response, swapping to a correctly profiled rotor will influence midrange and high-speed mixture behaviour. After installation, confirm needle settings and perform running checks to dial in performance.

Installation notes: remove the carb top per your engine's procedure, slide the rotor on aligning locating features, secure with the original retainers, and confirm smooth rotation across the throttle travel. Avoid using excessive force to prevent damage to throttle components.

Compatibility and inspection: offered as part number OS29183210 from O.S. Engine. Verify rotor profile and locating details on your carburettor before fitting and carry out a bench verification of throttle movement and mixture adjustments once installed.
