Replacement head gasket for FS-200S engines

This O.S. Engine OS44514100 head gasket set is a two-piece replacement for FS-200S and FS-200S-FI model engines, supplied as 2 pcs per pack. It forms the sealing interface between the cylinder head and crankcase and is a routine service item whenever the head is removed for maintenance or tuning.

The gasket maintains compression integrity and consistent head height, both of which influence idle stability and peak output in nitro RC engines. Fit a fresh gasket after head removal to prevent leaks that can upset fuel mixture and tuning settings.

Installation notes: clean mating surfaces thoroughly, remove all old gasket residue, align the gasket precisely before lowering the head, and follow the engine manufacturer's bolt tightening sequence and torque specifications. Avoid overtightening, and inspect for external leaks after the initial run-in.

Compatibility

  • FS-200S
  • FS-200S-FI

Will this OS44514100 gasket set fit FS-200S and FS-200S-FI engines?

Yes. This set is specified for FS-200S and FS-200S-FI models and is supplied as two gaskets per pack to cover a standard head service.

Should I replace the gasket every time I remove the head?

It is advisable to install a new gasket whenever the head is removed. Reusing an old gasket risks compression loss and unpredictable tuning, so replacement ensures a reliable seal.

How can I confirm there are no leaks after fitting?

After assembly, run the engine briefly at idle and part throttle while checking around the head for fuel or exhaust seepage. Once cooled, recheck fastener torque to confirm the seal.
