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

GT60 Gasket: Overview and Function

This O.S. Engine cylinder gasket is produced as an RC-scale replacement for the GT60 engine line. It seals the joint between the cylinder head and crankcase to maintain compression and prevent leaks that can upset idle and tuning response.

Compatibility follows the GT60 designation, so confirm your engine model before purchase. While the gasket does not alter performance directly, a consistent seal stabilizes combustion pressure and helps keep needle and carburetor adjustments repeatable.

Installation notes - ensure mating surfaces are clean and free of old gasket residue, seat the gasket flat on the cylinder face, and tighten head bolts evenly in a cross pattern to avoid distortion. Do not overtighten and verify flat seating before final torque. Re-inspect after initial runs for any signs of seepage or compression loss as part of normal tuning checks.

Handling and service tips - replace the gasket whenever the cylinder is removed for overhaul or if you observe fuel leakage or compression problems. Keep spare gaskets stored flat to prevent folds that could impair sealing performance.
