450 cam

just bought a 450 cam to do the swap, is the auto decompression mechanism supposed to have a spring on it? i was thinking the last swap i did on a 250f had a spring, the cam i just got dont have a spring

It very definitely is supposed to have a "mousetrap" spring coiled around the pivot of the flyweight. It won't work properly without it.

thanks, thats what i thought...anybody have a spring?
