Well what I did was move the wheel back as far as I could (credit to you for that)
, then I did the wheel alignment trick (measuring from the middle of the nut on the frame to the nut/bolt on the wheel. I have both at exactly 16.5 so I know the alignment is good.
The belt is snug but not REAL tight. I took her around the block in the rain (couldnt resist) at about thirty and didnt hear any strange noises...but I am sure I will need to get up to speed this weekend after this darn rain
