O.S. Engine OS27981710 Carburettor Retainer 60B carburettor part for engine carburettor assemblies  [OS27981710]

Carburettor retainer overview

This O.S. Engine OS27981710 carburettor retainer 60B is an RC-scale accessory designed to secure a carburettor within an engine assembly. It serves as a mounting and locating element that keeps the carburettor aligned with the intake and throttle linkage during running and adjustment.

Use this retainer when replacing worn mounting hardware or when reassembling an engine after service. Typical installation is straightforward: position the retainer to locate the carburettor against the intake flange, align the throttle linkage and bind points, then tighten fasteners evenly to maintain alignment. Keep fasteners snug but avoid over-torquing to prevent thread or housing damage.

For tuning and setup, the retainer helps maintain consistent carburettor orientation so needle adjustments and throttle responses remain stable between runs. Inspect the retainer during routine maintenance for deformation or wear that could affect carburettor seating and throttle action.
