Picked up a Husky 455 from TSC on saturday. I finally oiled and fueled her up last night. I should have noticed but I didn't,fired her up and just letting her warm and seat in when whammo chain comes right off! It was on backwards!! ARRRG It hit the chain stop and put a few burrs on the drive teeth,so I put on my brand new spare the right way and I cut for a few minutes. I'm liking it so far. Who was the bigger idiot,the chain installer or me for not checking???
