Thanks for the info guys. I don't think I have the same problem you
guys do. The chain is the perfect length, and it is not rubbing on
the top front of the chainstay.

It is rubbing on the inside top edge right back in front of the drop
out. The chainstays kindof angle in from the drop-out to where they
attach to the frame. Because of the thickness of the tube that
protrudes inwards to the gears it rubs right there.

I am not sure if adding a idler will do the trick, but I might give
it a try. I am getting tired of the noisy tubes anyway. At a
minimum I need to flare the ends I think to quiet them down.
