FSa-56 pushrod for FS engines

This O.S. Engine pushrod is an RC-scale replacement part intended for FS engine line maintenance and tuning. It serves as the linkage between rocker/valve components and the engine's valve control mechanism on model glow engines, and it is designed to be used where FSa-56 style pushrods are specified.

Fitment and compatibility are limited to FS engine parts; confirm the original pushrod designation on your engine before installation. The component functions as a mechanical linkage and plays a role in fine adjustments to valve timing and clearance during engine setup.

Installation notes: inspect the mating surfaces and rocker pins for wear, ensure smooth articulation without binding, and verify clearance through the full stroke before final assembly. For reliable operation on an RC model engine, check for proper seating and secure retention of any retaining clips or pins supplied by the engine manufacturer.
