Carburettor 60L Mixture Control Valve OS29083600 Compatible with O.S. Engine  [OS29083600]

Performance tuning notes for the 60L mixture valve

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.

Used as a tuning aid, the assembly lets you make accessible needle and idle corrections without removing the carburettor. On fitting, ensure the valve lines up with the linkage and that there is no binding across its range to avoid erratic idling.

For best results during tuning, make minimal adjustments, observe engine behavior under load and at idle, and finalise settings with the engine at operating temperature. If unsure about compatibility, check the valve's mounting geometry against your existing carburettor components before committing to installation.
