I,m not shure which ball you are refering to. The one under the accel. pump can get stuck if someone has put the wrong ball in it. The only spring that comes in the kit is the one 3.825 under the little T. You can use the old one. I generaly don,t pull it out. If it has the Grose -jet Greg is referring to you can replace it with the conventional needle & seat that comes in the kit.
