I'm assuming you have already cut your nocks in?If you have and can't adjust it by cutting one side deeper than the other,you might try this little trick.I use this when I by an old collectable recurve with twisted limbs.Get a buddy to grab one end and you grab the other.Twist the limbs toward the center and a little beyond,don't get real crazy.Hold it for a few seconds(60) and then string backwards for awhile the longer the better.Depends on how bad you want to shoot it and the patience you have.You can use light heat,like a hair drier after moistoning the rawhide,but it will probally pull back to where it was.You can also try sanding the hide to make it thinner on the strong side.
