Looks like I may have found my problem on this vibration between 1700 and 2100 rpm. Three cylinders look great inside, but the #2 is very oily. I knew something was wrong when I pulled the top plugs because the #2 looked oily and black while the others looked fine and when I pulled the #2 bottom plug, it was black and filled with oil. There is quite a bit more oil laying in the cylinder as well. Looks like I will have to redo that cylinder. It must not be screwed up too bad as the walls look okay, from what I can tell. I'm waiting on my compression guage to come so I can check things out better.
