Hey, so here are a couple of pictures of the carb I soda blasted, a before and after sidexside comparison. To minimize wasted soda remove the hard, crusty stuff 1st. There are pre-built guns, but I had good success with the unit I built.
One last suggestion, wear a mask, the stuff tastes terrible!

Happy blasting!
Steve
