My Husky came with a 20" 80 dl .325 setup. All of the catalogs show 78 and 80 link chains for the 20" Husky which is more common? This is my first real saw and Im loving the power it puts down!
If you get the oregon solid hard nose laser plus I think it is either 80 or 81. At least the medium tip one I have. It might be kind of similar for solid replacement nose bars.
