I bought a replacement chainsaw blade for my 20" Poulan at Menards in Kearney and it wasn't the right one. I took it out of the package put it on the chainsaw and could see that it wasn't fitting the cogs on the end of the bar right so I took it right off so it wasn't even run on the chainsaw.  I don't know when I will make it back to Kearny so I figured I would try to sell it for what I gave for it which was $18.36. It's a D70 20" for a Craftsman, McCulloch, Echo, Homelite or Poulan.
