QJs & TQs were spread bore. The size difference of the pr & sec bores of say, a 650 Edel AVS does not make it a spread bore. It is a square bore carb, as are all Edel/Carter AFB/AVS carbs.
What differentiates a square bore from a spread bore is the centre lines of the t/bores, relative to the mounting holes.
