FSa-110 Intake Manifold OS44969400 by O.S. Engine for FS-Series  [OS44969400]

FSa-110 manifold overview

Catalogued as O.S. Engine OS44969400 FSa-110, this intake manifold links the carburetor to FS-series glow engines and is offered as a replacement component for hobby engines bearing the FSa-110 identifier.

In service the manifold directs the fuel/air charge from the carburetor into the engine intake flange while preserving alignment and a sealing interface. Prior to fitting, inspect the flange faces and the engine mating surface to ensure they are free of nicks or gaps that could cause air leaks.

Fitting guidance: use the original engine fasteners when practical, check seals and O-rings for integrity, and torque bolts in stages to maintain an even flange. Note that intake shape can alter throttle characteristics, so monitor engine behavior after installation and make small carburetor tweaks if necessary.
