FS Engine Parts Compatible Rocker Support GF40 - OS49464000 by O.S. Engine  [OS49464000]

Product Summary and Role

The GF40 rocker support is supplied as an RC replacement part to stabilise the rocker shaft zone on FS-series engine assemblies. The "GF40" label identifies the component and indicates it is intended for use with FS engine parts configurations rather than functioning as a standalone engine.

It positions the rocker assembly to assist in maintaining valve geometry consistency during tuning and rebuilds. This copy emphasises compatibility and role in setup rather than detailed installation steps.

Install this support when replacing a damaged rocker mount or when fine-tuning rocker shaft alignment on FS-series RC glow engines; always check physical compatibility with your engine layout before completing assembly.
