I am trying to replace my plastic (stripped) hot start plunger but I can't figure how to get it off so I can put the new plastic one on. The diameter of the cable just gets larger toward the hot start lever,so it won't slide up and out that way . . . and it doesn't pull out other way either because the actual plunger part (not plastic) is too large in diameter as well. Thx in advance for any help.
