O.S. Engine OS44369400 Intake Manifold FSa-72  [OS44369400]

Intake manifold for FS engines

This intake manifold is an RC-scale engine part intended for use with O.S. FS engine components.

The design focuses on being a direct-replacement intake route that supports basic installation and tuning tasks on small glow engines, serving as a mounting and air-path component rather than a performance modifier.

Installation notes: align the manifold to the engine flange and manifold mounting points, confirm gasket seating if used, and verify throttle linkage clearance before first run; this avoids common fitment issues on assembled RC powerplants.

Tuning role: the manifold maintains consistent airflow path and mounting stability, which helps preserve carburetor alignment and repeatable idle characteristics when adjusting needle settings or testing fuel mixtures.
