What did you use to crimp the link? The 2-4mm sounds like alot if difference unless you crushed the link. If you plan on doing much bike mantinace I would look into investing in a chain tool to brake/rivet masterlinks. You can get them for little money and they make things much easier. I would check with calipers the link widths and your master and if it's binding can cause sprocket or chain damage. That could be dangerous for you and others around you if something fails. So, at the very least I would get a new link and ty again.
