O.S. Engine OS29083600 Mixture Control Valve Assy 60L - Carburettor Part for RC Engines  [OS29083600]

Mixture control valve assy overview

This is an RC-scale mixture control valve assembly intended for use with O.S. carburettor parts and related replacement components. The 60L designation identifies the valve size and its role in adjusting fuel/air mixture for small nitro RC engines.

In practical use the assembly provides a user-accessible point for fine adjustments to needle and idle settings without replacing the main carburettor body. When fitting, confirm alignment with the carburettor linkage and ensure the valve operates smoothly through its travel to avoid uneven idling.

For tuning, treat the part as a precision adjustment component: make small incremental turns, observe engine response, and finalize mixture and idle with the engine at normal operating temperature. If you are uncertain about fitment, compare the valve shape and mounting points to your existing carburettor parts before installation.
