FS-200S & FS-200S-FI Cam Cover Gasket O-ring OS44501110 - O.S. Engine  [OS44501110]

Seal for FS-200S cam cover

This O.S. Engine cam cover gasket is manufactured as a replacement O-ring tailored to the FS-200S series of nitro RC motors. It restores the cam cover seal to avoid fuel seepage and crankcase leaks that harm running consistency.

Fitment applies specifically to FS-200S and FS-200S-FI. Do not assume interchangeability with other engine codes; always match exact model identifiers when selecting parts.

Fitting guidance: remove contaminants from the groove and the cover face, position the O-ring without overstretching, and tighten the cover evenly. Use a minimal amount of O-ring safe lubricant to assist seating and discard any ring with visible damage.

Service impact: maintaining a good cam cover seal helps keep crankcase pressure stable and prevents fuel drips that can upset mixture settings, so replace worn seals when you service or overhaul the engine.
