60B Carburettor Retainer Summary

The O.S. Engine OS27981710 carburettor retainer 60B is an RC-scale accessory made to hold a carburettor in the correct position within an engine assembly. It serves as a locating and mounting element that ensures the carburettor stays aligned with the intake and the throttle linkage during operation and adjustment.

Fit this retainer when replacing worn mounting hardware or after reassembling an engine following service. Typical fitting is straightforward: set the retainer so the carburettor seats against the intake flange, align throttle linkages and bind points, then tighten the fasteners evenly to preserve alignment. Keep fasteners snug but do not over-torque to avoid damaging threads or the housing.

During setup and tuning the retainer maintains consistent carburettor orientation so needle settings and throttle response remain repeatable between runs. Check the retainer at routine service intervals for any deformation or wear that could compromise seating or throttle action.
