Piston suitable for FS-200S units

The OS44503200 piston is a replacement component compatible with O.S. Engine FS-200S and FS-200S-P models. It is used to reestablish compression and to return predictable running characteristics to glow engines in scale models.

When a piston shows wear, replacing it improves ring sealing and reduces blow-by that negatively impacts idle and throttle response. Match the piston to the correct cylinder and fit the prescribed ring set when carrying out the service.
