So it is not factory but does clearly show that they added a spring to the pump lever on the 4300 model carburetors. So in some sense I guess some of them did have a return spring upfront although comparing a 4300 to a 4100 is apples and oranges. Just thought I'd share .

  Had to remove the clip to reposition the lever....you're right....not so flimsy when you try to remove it.
