YS Engine YSS2023 Insulator Set Screws for 56SR  [YSS2023]

Secure insulator fasteners for 56SR engines

This insulator set screw kit is a precision spare for securing the insulator to the intake manifold on YS Engine 56SR series model engines. The hardware maintains the mechanical joint between insulator and manifold so mounting points remain consistent during routine maintenance and bench setup of RC model engines.

For installation, align the insulator with the manifold, start each screw by hand to ensure correct thread engagement, then tighten progressively and evenly until firm contact is made. Avoid over-torquing to prevent thread damage; the fasteners help preserve insulator position when adjusting carburettor or intake timing on the model engine.
