Also, I had a dragging sound when I would rotate the drivetrain. I found it was the 2 metal shims they have you install between the center spur gear and the uprights. I removed both and there was no longer a drag. I may need to reinstall 1 of them after I run it, but so far it doesnt seem to be sloppy without the shims.
