O.S. Engine OS27981710 60B Carburettor Retainer for Engine Carburettor Assemblies  [OS27981710]

Overview of Function

The O.S. Engine OS27981710 carburettor retainer 60B is manufactured for RC engine use to secure the carburettor within the engine assembly. It provides a locating and fastening role that keeps the carburettor aligned with both the intake flange and the throttle linkage during operation and while making setup changes.

Fit this retainer when you need to replace worn mounting hardware or after reassembling the engine post-service. Installation is generally straightforward: place the retainer to locate the carburettor against the intake flange, align throttle linkages and mounting points, then tighten fasteners evenly to preserve correct alignment. Ensure fasteners are snug but do not over-torque in order to avoid damaging threads or surrounding components.

When tuning, the retainer helps maintain a consistent carburettor orientation so that needle settings and throttle response remain dependable between runs. Inspect the retainer as part of regular engine maintenance and replace it if you find cracks, distortion, or a loose fit that could affect carburettor seating.
