  • Holley Carb plating

    There are a lot of us out there trying to restore Holley carburetors to their original finish. I am using the Copy Cad kit. I am glass beading the fuel bowls and main body. I then plate with the zinc. It looks pretty good at this point (maybe a little shiny). When I dip into the yellow chromate solution, my parts look way to yellow and shiny. They look just like the steel parts that I have plated. I am wanting the flat "golden" color that these carbs were originally. Should I be using the olive drab dichromate solution? Any help will be greatly appreciated.

    Sounds like you have too much brightener in the Copy Cad. It needs to plate dull.

      Mach, ive read that as soon as you put the yellow on imediately redip you carb. into a 5% with muratic acid and distilled water for about 10 secands and then redip into distilled water bath. Im getting ready to try it on a Rochester carb. stay tuned ill let you know how it comes out.
