Hello Michelle,
It won't be the needle bar that is out of alignment it will be the timing, you can do this yourself but you will have to have a lot of patience because you may not get it right first time, if you want me to tell you how to do it, e-mail me drivewithken@blueyonder.co.uk and I will type up full instructions for you.
