I hear this complaint a lot. If the problem's not your bar and you're not an experienced filer, make this tool and check the length of all your teeth. Don't eyeball it. Use a nylon core stop nut with the nylon drilled out -- enough will remain to allow the nut to be turned by hand.
Find the shortest tooth and sharpen it. Adjust the nut so the space between the nut and the bolt head is just snug when placed over the short sharp tooth. File all other teeth to the same length, using the tool as a gauge. Finally, using a filing gauge, cut down all the depth gauges to the same height. You are done. If that chain still cuts crooked, look for another cause.
