Yes it could wear out/malfunction. Check your compression if it is higher than what the manual states (65 psi I think)I would first adjust your valves and recheck. Your valve adjustment is off it can effect the compression release operation (thanks DL). Always check your compression with the throttle open.
It looks sort of like a cam lobe. It has a low tension spring that holds it in the up position. It also has a counterweight opposite the lobe. While cranking the lobe is held in the up position by the spring and it locks in place by the drag of the rocker arm. It bleeds off some compression by slightly opening the exhaust valve while cranking. Once the engine starts the centrifugal force on the counterweight opposite the lobe deactivates it.
