56SR Insulator Mounting Screws YSS2023 by YS Engine  [YSS2023]

Mounting screws for the 56SR intake insulator

This kit supplies replacement insulator screws intended to fasten the insulator to the intake manifold on YS Engine 56SR series model engines. The components stabilise the insulator/manifold interface so alignment and sealing are preserved during normal use and workshop servicing.

When fitting, check that the insulator and manifold faces are flush, start screws evenly, and bring them up to a secure fit using small increments. Do not over-tighten; correct fastening helps keep the insulator location stable during carburettor adjustments and tuning sessions.
