GT60 Reed Valve Assembly for RC Engines - OS28616000 by O.S. Engine  [OS28616000]

GT60 Reed Block Replacement

This reed valve assembly is a direct replacement designed for the O.S. Engine GT60 series of RC two-stroke engines. It functions as the intake reed block in glow-engine induction systems used on scale radio-controlled models, describing its role in the engine intake path.

Compatibility is limited to the GT60 designation indicated in the product name, so verify your engine model before ordering. The assembly replaces the reed block section and is intended for hobby use on scale RC engines only.

Installation and tuning notes:

• Remove the engine carburetor and intake housing to access the existing reed assembly, and follow the engine manufacturer's service procedure for safe disassembly.
• Inspect mating surfaces for flatness and cleanliness before fitting the new reed assembly to ensure sealing and consistent airflow.
• When reinstalling, use the original gasket or a proper replacement to avoid intake leaks that can affect idle and throttle response.
• Tuning: reed condition affects throttle feel and midrange power; check for reed flutter or leaks during bench runs and adjust needle settings and carburetor synchronization accordingly.

Maintenance tips:

• Check reeds periodically for chips or deformation and replace if any damage is found.
• Keep surrounding mounting hardware torqueed to specification to prevent air leaks and ensure repeatable engine behavior.
