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

How the GT60 Gasket Impacts Tuning

This O.S. Engine cylinder gasket is an aftermarket replacement for GT60 model engines used in RC glow systems. It seals the interface between the cylinder head and crankcase to protect compression and prevent leakage that can undermine idle and tuning consistency.

Compatibility is tied to the GT60 marking; confirm the engine model before purchase. While the gasket does not actively tune the engine, a dependable seal stabilizes combustion pressure, which helps keep needle and carburetor settings consistent across sessions.

Installation notes - remove any old gasket residue and clean mating surfaces, position the gasket flat against the cylinder face, and tighten the head screws evenly in a cross pattern to avoid warping. Do not overtighten; verify flat seating before final torque. After first runs, re-check the joint for seepage or any drop in compression as part of standard tuning validation.

Handling and service tips - whenever you remove the cylinder for inspection or overhaul, fit a new gasket or replace it if you detect fuel or compression leaks. Store spare gaskets flat to prevent folding that could affect the seal.
