A slight twisting of the throttle shaft is the preferred method of fixing your issue. This problem is not uncommon and will reoccur . When it does, the drilled holes in the butterfly are going to have to be re-filled and start over. Not a good thing.
I don't see the need to remove the carbs and build a test fixture. Just lightly bend the shafts and be done with it.
