Those are accelerator pump carbs.
They may be 28's but also 26's
28's have 1 square diaphragm and the 26's have 2 ( 1 square and one triangular) on number 2 float bowl.
The location for the triangular one is un-machined with no cap on the 28's.
A pic of number 2 float bowl would confirm
I would un-blank the air screws and fit brass mains as they are more accurate than nylon.
Like for like brass and nylon do not flow the same amount of fuel.
