You can see the heavier spring in the top, is slotted, so it doesn't do anything initially. two springs like the toher one would like help the problem.

You can probably get some thing that will work at a local speeed shop. just ignore the applications on the packages. I have found gm pre hei springs work well on these.

You could grind a little off the weights too if you like, but with the long slotted spring you have, it won't help. AND there isn't a lot to the weights in those anyway, so if take much off, it becomes hard to get springs that are light enough.
