I've never had an issue of not being able to keep the end of the spring in the pocket. Make sure you have the right springs in the correct location. If they are the right springs it isn't detrimental to have the pig tail all the way at that perch. Once you drive the spring will usually settle. Make sure that the tip is just as far from the devot in the perch on each side. Once the springs settle a little you can re adjust them.
