DIY zinc plating of small parts

Many of the parts on my carburetors were in good shape, but the plating had worn off and they were rusty.  I think the original plating was cadmium.  You can buy easy-cad plating kits from places like Caswell and Eastwood, and that is certainly a good - though expensive - solution.

I decided that, with the internet as my teacher, I would try to plate small parts myself using a home-brew kit.
