QJ and TQ are similar in design, along with the AFB Carter and now Edelbrock carbs. Tuning just requires getting your head wrapped around it.
Seems racers all understand Holley style carbs and tuning using jets and air bleeds. Same thing, just a different way of going about it.
Then there are the Constant Vaccum or Constant Depression carbs used by the Limeys; SU and Stromberg. Plug those into your Funk and Wagnal's and figure out tuning them.
