My throttle won't spring back I took the spring off but I do not know how to put the spring on properly. I've actually been riding like this for a while now when I go wide open I'll just hit it back with my thumb but it's getting annoying so I thought I would ask for some help could someone show me on a video or something how to do this. I have a pic of the spring from the Manuel but it doesn't tell you how to put the spring on
