    chains fit a bit badly at first, but will loosen up in first 10 miles of running

    I sometimes have to file or grind the sprocket teeth to be a bit narrower for the initial fit.

    So do you think I need to file the sprocket teeth down

    Try wiggling the chain back and forth, use a screwdriver until the chain comes through far enough to grab with pliers, then PULL that s.o.b and it should come through. I had the same problem with 410H, wiggling and pulling did the trick.

    If you can make it fit for a while, it should loosen up, but if not, then look carefully at why it is not fitting - usually, the rollers are riding up on the teeth due to the top of the teeth being a bit long to let them slide all the way down - that is when you might want to file or grind just the edges of the teeth to make them pointier
