50ST Mounting Insulator Gasket - YS Engine YSS1024 for Glow Engines  [YSS1024]

Mount insulation for 50ST glow units

This YS Engine YSS1024 insulator gasket provides a compact insulating spacer for 50ST-class glow engines used in radio control models. It reduces conductive heat flow to the mounting surface and assists in maintaining proper cylinder head positioning under thermal load.

Install where combustion heat and vibration could alter mounting geometry; the small gasket helps separate heat paths and damp minor vibration. Prepare mating surfaces by cleaning and checking for flatness to ensure an even bearing and seal.

Practical notes: locate the gasket between the engine flange and the mount or between the head and backplate depending on your build, tighten bolts in a cross pattern to avoid uneven compression, and recheck alignment after the first run to confirm fitment.
