set screw for governor spring methods????

[UnderdogGN]

hi, im new to transmissions and wondering how exactly you are supposed to put a set screw in the governor spring. I am doing this because i want it to shift earlier and was told that a set screw adds weight therefor causing it to shift sooner?? What all do you need to do this?? Pics would be really helpful.
thanks
