GT60 Cylinder Gasket Seal - OS28614000 by O.S. Engine  [OS28614000]

GT60 Cylinder Gasket - Key Details

This O.S. Engine cylinder gasket is a replacement part intended for the GT60 model engine family in RC glow applications. It forms the sealing interface between the cylinder head and crankcase to preserve compression and block leak paths that can disturb idle and tuning stability.

The GT60 designation defines compatibility; confirm your exact engine code before ordering. The gasket itself does not tune the motor, but a reliable seal keeps combustion pressure consistent so needle settings and carburetor trims remain repeatable between runs.

Installation notes - clean the mating surfaces thoroughly and remove old gasket material, lay the gasket flat on the cylinder base, and tighten the head screws evenly using a cross pattern to prevent distortion. Avoid overtightening and check for flat seating before applying final torque. After initial running, inspect for seepage or loss of compression as part of routine tuning checks.

Handling and service tips - replace the gasket whenever the cylinder is removed for overhaul or if you detect fuel or compression leakage. Store spare gaskets flat to avoid folding or creasing that could compromise the seal.
