My Poulon came with an Oregon chain and I recently bought and installed a new Oregon chain. The new one was whatever Oregon recommended for my saw but now I realize there is a diference between the two. The old one looked like this first picture where the raker is just sitting there by itself. The new one looks more like the second picture where the raker has another piece of chain right next to it. It looks like I have a very small amountof raker to knock down as I sharpen until I am hitting this adjacent thing. I was looking at how to use my new Stihl depth guide when I noticed the difference. I have the original and was going to put it back on and practice sharpening the raker. Now I'm a little confused about how or if I should be taking down this new raker as it needs it.
