That said I think I understand now. Bend the tang to the right which would loosen the spring slightly. Bending the tang right is the same as moving it a slot left.
Could it just be moved out of the slot to the left and rest against the circular knob? Even maybe soldered to the side so it would stay put.

That is correct. Removing the spring from its current position and moving it to the left (say 12:00 to 11:00) is what you want to do. Give that a try and if the fan stays on too much then take my riskier approach and bend the end of the tang. I've heard guys succeed with moving it out of the slot and leaving it loose, but never had an update whether the pin might migrate farther around since it is now free floating.
What can sometimes happen is you move the tang too far and it lets the fan stay on under 180° and your thermostat is a little lazy and keeps temps at 185° -- and the fan will always be on trying to fight the thermostat.
I really didn't want to post this ugly photo but it does show the bent tang that allows the center pin to be slightly more counter-clockwise. In this particular case the slots on the pin were originally in a 9:00/3:00 location and you can see a very slight pitch on the pin now.
I'm also wondering if a slot might not be cut with a Dremel tool about half way between the stock slot and the outside of the casting?
