Durable carburetor insulator for 50ST

The YS Engine YSS1022 is a replacement carburetor insulator intended for 50ST-class RC nitro engines, providing a durable spacer between the carburetor and engine flange. It is offered as a service part for maintenance and component replacement.

Fitment caution: compatibility is stated for 50ST models; do not assume fit for other engine families without checking the parts list. Installation involves separating the carburetor from the flange and refitting with proper torque values from the engine documentation.
