Distributor curve help needed

I believe this was a points distributor that someone put a Pertronix unit into. I don't have a long looped spring, so should I replace the heavier black spring with a lighter one?
You could try that.
Or if your good with shaping little things, make the black spring's loop a little longer.
Just a heads up that being a spring, not going to be able to bend it too many times.
I'm sure we can find you a long looped spring if you want.
