Common sense should tell you that your sprocket is either bent, or it's not aligned properly.

Aside from the fact that sprockets are rarely perfectly true in the first place, it doesn't take a noticeable bend to put a tight spot in a chain.

I installed my sprocket incorrectly, and broke a chain racing. Things happen.

That's why I run a 3/16" street chain. Snapped too many normal sized chains when I was a fly weight.
