I wouldn't recommend it. Sandblasting will not get scale and gunk inside small drilled passages - and that's usually where the problem is. Also bits of sand caught in these passages when you are finished can cause unpredictable carb performance after reassembly.

A better approach is a long soak in a strong cleaner. I've had good luck with sodium hydroxide solution (get it at the paint store). Also chlorinated solvents like perchlorethylene are effective. Muriatic acid should work, but you need be watchful for corrosion on machined iron and brass surfaces. Also good idea to rinse the parts in a baking soda solution to neutralize any residual acid before reassembly.

Safety warning: All of the above are NASTY! Use only with good ventilation (ideally outdoors), wear eye protection and keep the stuff off your skin!
