I wasn’t sure if I was gonna be able to pull this one out of the chipper or not. The choke and throttle shafts were froze up in the castings and the throttle body and linkage looked pretty bad. It actually came out much better than I would have thought.

I just hung the pieces together for the picture and am waiting for a kit to finish it up. I could still use some advice as to what I need to do to re-jet it for a 216. I’m still working on a few ideas for adapting the larger throttle body to the 216 manifold.

Denny, how did you get the metal so nice and purty?

Joe

Several steps involved Joe, first off soak it all in Gunk Carburetor Cleaner over night, (at least 24 hours). Then attack them with the scrubbing bubbles, that be New Blue Cheer in some hot water and a SS wire toothbrush and stiff parts brush. After a good rinse that does it for the Zinc castings or any thing that isn't rusty.
For the parts that are rusted, like the throttle body and linkage it goes into the D-Rust-It tank. A couple of hours are usually good if it's not to terribly corroded then back to the scrubbing bubbles.
At this stage you will have a throttle body that looks like a new casting with a rather flat cast gray finish. You can paint it or the other steel parts if you choose with cast blast, or an black Rustolium, or a clear, or plate them or just leave them bare to rust like most of the new ones were.
I some times follow up with a fine wire wheel on the pedestal grinder as I did on this one. Although the original cast iron parts were left bare I feel it helps to keep it looking nice if you do paint the throttle body.
As far as coloring the Zinc castings, I haven’t used any of the Eastwood products that simulate the yellow or yellow green chromate finish. A lot of the new Zinc casting are treated with a chromate or conversion or anodic dye I haven’t found any sources for these chemicals. Perhaps Jon, the “carbking” can give us some advice on how to treat the Zinc castings to make them look new again. That certainly would be the finishing touch to a well-done rebuild.

Carburetor original finishes

Jon.

There ya go guy, I was hopeing Jon would come through.
Jon how does one find this information on your site? The address is http://www.thecarburetorshop.com/Carburetorfinishes.htm but when I look for "carburetorfinish" or tips or how-to's etc., I can't find anything. I've spent many hours and printed out a bunch of your pages but just can't seem to find my way around your site.
Thanks for the article.

Denny - if you click on the link you posted, you get the page with the finishes (unless you are using one of the off-breed browsers). Our site is programmed for Internet Explorer; other browsers may have issues.

No Jon, I have IE6, maybe I said it wrong, I can see the page that you linked us to just fine that's not what I mean. When I go to your site I've never been able to find any of that information or any other information of that type before. I've never been able to find any referancer to a tips section there none of your headings lead a person to any instruction or manuals or articles.
