Engine Camshaft
The Automatic Compression Release (ACR) mechanism is integrated into the camshaft; if the internal flyweights or springs fail, the engine will not vent compression during the start cycle. This creates immense physical resistance when pulling the starter rope. Replacing the camshaft restores the mechanical decompression required for low-speed cranking.

Valve Cover Gasket
Excessive valve lash (clearance) prevents the rocker arms from engaging the decompression bump on the camshaft. Adjusting the valves to the manufacturer's specification (typically .004-.006 inches) is the primary service fix for a hard-pull symptom, and a new gasket is required to reseal the overhead valve chamber.

Flywheel Key
If the mower previously hit a hard object, the flywheel key may be partially sheared, which advances the ignition timing. This causes the spark plug to fire too early in the compression stroke, creating a combustion force that pushes the piston backward, resulting in a violent 'kickback' that feels like the rope is stuck or being ripped from the hand.
