How do you arrange the parts in the bucket. I guess you put the positive lead to one part of the steel, but what is the rest of the hook up like? And I guess you use water with baking soda in it? What ratio, etc.

Sounds interesting. We just bought an ultrasonic parts cleaner at my job to clean gummed up carbs, and it is terrific. No caustic chemicals, just water and detergent, and the carbs come out spotless in an hour or so.
