Anodizing Carbs & Heads
I wanted to know if anyone has ever taken their carb apart and had it anodized. Also, what about purchasing regular aluminum heads and having them hard anodized. There is a local company that will do the carbs for $75 and heads for $100 each. Seems like it might be a good idea.

I dont think you will Anodize a Carb Body , the are generally cast from a Zinc-Aluminium alloy that will only turn a smutty black . You generally use a Chromate solution on the
carbs , they call it a conversion coating .

I agree, I don't think this would work - and if it did-- I'm guessing that with pretreating the metal and then adding the anodizing layer - is it possible that you would change the geometry enough to screw up fuel and air flow - yes it may look good - but looking good may not be so important when you are a few miles off shore.....
these are just my thoughts

I can understand that. Just curious how the new Ultra series comes black. I would love mine to look like that because they are a polished carb right now that has the typical chalky white look now.

looked into doing the alum heads hard black. it was through the builder and it added quite a bit to the price. all the chambers had to be redone, redecked, valve job etc .

Not sure if this helps but I had my blowthrough carb powdercoated. Looked like new after 3 years of use... fuel spills on the coating never caused any degradation. Coating done by CSU carbs.

hARD ANODIZING last i knew was around 1000.00 fr a set of heads thats the millitary spec for marine use type.
Soft anodizing is much cheaper and dosent hold up as well by far. Hard anodizing has a draw back also as if is treated for too long the heads will become too soft and have to be trashed.
