GT60 Reed Block Replacement - OS28616000 for RC Two-Stroke Engines by O.S. Engine  [OS28616000]

Replacement reed block for GT60 series

This reed valve assembly is offered as a direct replacement for O.S. Engine GT60 two-stroke RC engines. It constitutes the intake reed block used in glow ignition induction systems on scale radio-controlled models and is specified as the intake component for that engine series.

Intended compatibility is limited to the GT60 designation in the name; verify your engine model before ordering. The assembly replaces the reed block section and is designed for hobby engine applications only.

Installation and tuning notes:

• Remove the carburetor and intake housing to access the reed assembly, following the engine manufacturer's safe service steps.
• Check all mating surfaces for flatness and cleanliness before fitting the new reed block to secure a tight seal and consistent airflow.
• Use the original gasket or a correct replacement when reinstalling to prevent intake leaks that can upset idle stability and throttle response.
• Tuning note: reed condition influences throttle feel and midrange power. Watch for reed flutter or sealing faults during test runs and adjust needle settings and carburetor balance accordingly.

Maintenance tips:

• Periodically inspect reed petals for damage and replace at the first sign of chips or deformation.
• Keep mounting hardware torqued to specification to prevent air leaks and maintain reliable engine behavior.
