FS-95V Intake Manifold for O.S. Engine OS40969400  [OS40969400]

FS-series Intake Manifold Overview

This intake manifold is an RC-scale replacement part for the O.S. FS engine family, supplied as the FS-95V variant. It serves as the airflow interface between carburettor and engine, intended for hobbyists who maintain or tune FS-series glow engines. The design focus is on reliable airflow routing and repeatable fitment within the FS parts group.

Installation is straightforward but precise alignment matters: use the correct manifold gasket, align the flange surfaces cleanly, and tighten fasteners progressively to avoid twisting the manifold. After installation, check for air leaks at the joint and around the carburettor mounting to ensure consistent idle and throttle response.

In tuning terms the manifold contributes to throttle transition and responsiveness; small changes in manifold sealing or orientation can affect mixture behavior at low to mid throttle. Use incremental adjustments to needle settings and confirm changes on the bench or track to find the preferred setup.
