For some definition of "snugly". It's really easy to tighten a chain so much that the saw won't run. Loosen it a bit, and the saw cuts fine yet it's easy to pull a bit of the chain out of the slot (the latter with the saw off). At least, that's the case for the cheap/old saws that I've used... Don't worry I'm not running any saw without bar oil. Or rather, used motor oil, since I have plenty of that.
