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

Specific cam cover gasket for FS-200S models

This O.S. Engine cam cover gasket is supplied as a replacement O-ring for the FS-200S series of nitro RC engines. It restores the cam cover seal to reduce fuel seepage and prevent crankcase leaks that can affect engine tuning.

Applicable models are FS-200S and FS-200S-FI only. Always match the exact engine codes when ordering parts to ensure correct fitment.

Fitting advice: clear the cam cover seating area of dirt and burrs, fit the O-ring without stretching it beyond its relaxed size, and align the cover evenly before tightening bolts. Use a small amount of compatible lubricant if needed, and replace any ring with visible damage.

Effect on tuning: a correctly fitted cam cover O-ring maintains stable crankcase conditions and prevents fuel dripping that may force needle adjustments or produce unstable running; change questionable seals during tune-ups and rebuilds.
