OhioBurner, like someone else said check your bar to figure out what size you need. I run a 3/8 pitch with a .050 bar groove on an 18" bar that runs 66 links. I run chisel chain with no antivibration or reduced kickback features. If you run the same chain you'd just need a longer loop therefore more links. Check you're bar it's stamped into the steel.
localLEE, Tom ain't no pup. He sharpens chain just fine. Sharpens his Stihl chains the same way he used to sharpen those crappy Oregon chains. Sorry you're such a Oregon fan. Didn't mean to hurt your feelings. I'm sure Oregon chains are really quite awesome and I've just been surrounded by incompetents my whole life. I'll run right out and buy a couple to put on my really great Husqvarna chainsaw that rarely ever sees any action because of its unwavering suckiness. Hope this makes you feel better
