Found the problem. Deck was bent at the spindle mounting holes causing blade to not be level, probably from when I broke a previous spindle when I hit an obstacle. Found the solution on this video...

Didn't need the big tool shown as the metal is not that thick. I used a short straight edge across the surface to verify the bend. I placed a block of wood under the bend and wacked it with a hammer. Pretty simple fix.
