Dennis, I had this same issue, brand new saw. All the way through the stroke the top of the blade was forward of the bottom. I found info on Steve Goods site and tried this. It worked very well, blade is 90º front to back now. Raise the back of the table, for me is was 1/4". Made this out of walnut and a 3/8" dowel. I will be haveing a friend make a better one out of metal, but this works fine.
Good luck!
Pete
