So while sharpening my new Oregon chain, I noticed that there seemed to be a cutter missing where it was joined together. Reading through the forum, this seems to be fairly normal and most people say not to sweat it. Two questions: 1) I didn't notice any dishing while limbing, but will it cut straight through bigger wood if it's got 17 cutters on the right and only 16 on the left? 2) Why not have a cutter where it is joined? (The chain has 68 drivelinks.) Thoughts???
