FSa-56 Pushrod — Replacement for FS Engines

This O.S. Engine pushrod is an RC-scale replacement part intended for FS engine line maintenance and tuning. It connects rocker and valve components to the engine's valve control mechanism on model glow engines and is made for applications specifying an FSa-56 style pushrod.

Fitment is limited to FS engine parts; confirm the original pushrod designation on your engine before installation. The component acts as a mechanical linkage and can affect fine adjustments to valve timing and clearance during setup.

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