Hood spring question

My question is on a 67 barracuda do you have to load the spring as in giving it a full turn somehow for it to hold the hood open? The way it is now i have to use a prop stick and dunno if the springs are just that worn or if I just assumed wrong when I initially installed them. The car didn't have them on to begin with so I have nothing to refer on what the stiffness of the hinges should be but I'm pretty sure it's not what I have lol
I just got done dealing with this I'm a thread I probably in Body & Trim. But I had one of the springs that had came off of its post and I had to recoil it and preload it. Oddly enough though when I had one not connected the other one would hold the hood up by itself. They're on their extremely simply just are held on with those retainer Clips like you put on the end of a little red wagon to hold the wheels on LOL I don't know what they call them. But there's one that holds the main hinge on at its other end and one that holds that spring leaver on. I bought some new ones at Ace Hardware.
Remember leverages your friend and your enemy, BE CAREFUL!
