Because chainsaws aren't designed for combat. They'd be dangerous to you and whoever you happened to be with, they run out of gas, and the teeth can break; at that point, you'll be carrying an incredibly heav, dull, useless blade. They also would take time to kill the zombies, and one at a time, too; if you've ever cut down a tree or watched someone do it, you'll notice that it's not an incredibly rapid affair. Sure, it'd be effective enough against a person, what with the organ trauma and all, but I don't imagine the average zombie's gonna go down without massive trauma to the central nervous system. Besides, I'd want to engage zombies at the furthest distance that I could, no sense letting them get close enough to hackon if you can help it.
