The spring goes under the belt.
When the belt is stretched tight to drive the blades it lifts up a bit.
Also despite the parts diagram showing the spring fitted long side to the deck, short side to lever, I find they work much better the other way around.

Thanks again, bertsmobile1. It only worked under the belt, but I was worried I had something wrong. And I was wondering if I could reverse the spring's orientation, as you mentioned.

I have no idea why but a couple of call outs had the spring detached from the deck when mounted as per the diagram.
Note these springs had a U at both ends the spring shown in the diagram has a Z bend on one end.
Don't know is there was a design change or Scotts Springs re different to Murray springs.
