chain saw mill

Hey I have a homemade chainsaw mill, sometimes it cuts straight, sometimes it doesn't haha. If its pulling to one side I am guessing one side of the chain is sharper then the other. Would it pull to the dull side or the sharp side? Thanks

Hey guys, First post here, so try to take it easy. I am a woodworker and have been for about 5 years now. I recently got into green woodworking, and it necessitated me harvesting some of my own wood. Well, I went pretty big on my first haul and now I have a 20', 30" dia burr oak in my garage...
