Insulator Gasket for 50ST Engines YS Engine YSS1024  [YSS1024]

50ST insulator gasket overview

The YS Engine YSS1024 insulator gasket is made for 50ST-type glow engines and serves as a thin insulating layer between engine components and mounting points. It helps lower direct heat conduction to the mount and supports consistent head alignment under operating conditions.

Use the gasket where heat and vibration might affect mounting geometry; the spacer reduces heat transfer and provides minor vibration isolation. Ensure mating surfaces are clean and flat to get a uniform seal and correct alignment during installation.

Fitting guidance: position the gasket either at the engine flange or between the cylinder head and backplate as your setup requires, tighten screws evenly to prevent uneven compression, and verify alignment after an initial operating session.
