Precision head gasket set for FS-200S and FS-200S-FI

The O.S. Engine OS44514100 gasket set provides two replacement gaskets intended for FS-200S and FS-200S-FI engines. It replaces the sealing layer between cylinder head and crankcase and is recommended whenever the head is removed for service or adjustment.

This gasket preserves compression and consistent head spacing, both critical to steady idle and repeatable top-end performance on nitro RC engines. Installing a new gasket after head removal reduces the chance of leaks that can change mixture and tuning behaviour.

Fitting advice: remove old gasket material and degrease both mating faces, position the new gasket squarely, then torque head bolts in the manufacturer specified pattern and values. Do not exceed recommended torque and verify there are no external leaks during initial runs.

Compatibility

  • FS-200S
  • FS-200S-FI

Can I reuse the old gasket if it looks intact?

It is not recommended. Even gaskets that look undamaged can have compressed areas or microscopic defects that lead to slow leaks; replacing the gasket ensures a secure seal.

What symptoms indicate a failing head gasket?

Loss of compression, unstable idle, increased smoke or inconsistent peak power can all point to a compromised head gasket. Check the head joint and replace the gasket if leakage is suspected.

Any best practices for cleaning the mating surfaces?

Use a solvent and a soft scraper to remove residue, avoid gouging the surfaces, and finish with a lint-free wipe. Ensure both surfaces are dry and free of oil before fitting the new gasket.
