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

Service and fitting notes for the FSa-110

Listed as O.S. Engine OS44969400 FSa-110, this intake manifold provides the intake connection for FS-series glow engines and is offered as a replacement where the FSa-110 specification applies.

The manifold conveys the fuel/air mix from the carburetor into the engine intake flange while preserving alignment and a sealing surface at the mount. When servicing, carefully examine the mating faces on both parts to ensure there are no imperfections that could cause leaks.

Installation advice: fit using original engine bolts if they are in good condition, replace any compromised gaskets or O-rings, and tighten mounting screws evenly to avoid warping the flange. After installation check idle and throttle response and make small carburetor corrections if required.
