FS Camshaft FSa-110 Compatible with FS Engines - O.S. Engine OS44962000  [OS44962000]

Camshaft Specifications and Use

The FSa-110 cam is identified as O.S. Engine OS44962000 and is supplied as the replacement cam for FS-series glow engines. Below are concise, application-focused notes for hobbyists carrying out maintenance or tuning work, including fit considerations, installation reminders, and the cam's role in timing and driveability.

Compatibility and role: sold as a camshaft spare for FS-engine maintenance and rebuilds, this component sets valve timing and lift parameters. Always check endplay and align the timing marks when installing to maintain correct ignition and valve sequencing.

Installation notes: carefully inspect cam lobes and journals for any defects, fit bearings or bushings according to the engine manual, and verify clearance with the cylinder head and valve train while rotating the engine by hand to detect interference.

Tuning impact: camshaft wear affects breathing and the low-to-mid rpm band; swapping in a matching FSa-110 can return the engine to its intended timing behavior without immediate carb or ignition changes.

This camshaft is intended for use as a direct service part during overhauls or timing restoration; confirm compatibility with your specific engine variant prior to final assembly.
