Aluminum carbs have a clear hard anodize coating. Have you tried non-acid rust removers? The 'corrosion' is oxides of metals in the fuel system, steel from the fuel line, aluminum from the fuel pump or carb interior, or galvanize from inside the tank, etc. Different oxide removers, aka rust removers, will have different effect on different oxides. I guess Zep quit making Rust Eraser, dang it, I found it was the most effective oxide remover in most cases, rust or 'corrosion'.rebelrouser wrote: ↑Wed Mar 20, 2024 8:37 pm I don't believe that ford autolite two barrels had a chromate coating.

Re: carburettor cleaning
That is the 2100 series Ford carb. It is very similar to the 4100 4 barrel. The body of the carb is aluminum and were originally left natural, no finish . Steel pieces were zinc plated and usually chromate applied. There is a couple pieces , choke housing and accelerator pump housing , that are zinc castings and these pieces had a chromate finish similar to this 4100 carb.rebelrouser wrote: ↑Wed Mar 20, 2024 8:37 pm I don't believe that ford autolite two barrels had a chromate coating.

Here is a 4100 carb that I have restored for a 1965 Mustang. The next picture is an Autolite 4300 4 barrel carb, I retored for a 1968 Cougar. The main body of this carb is zinc, which has chromate finish, not aluminum.

Re: carburettor cleaning
I assure you, aluminum carburetors and carb parts, AFB, Autolite, T-Quad, SU, Weber, Solex, Mikuni, etc, etc, have a clear anodize coating for corrosion resistance. Otherwise, they would become "corroded" in a very short time, as we see raw aluminum most certainly does. Vigorous abrasive cleaning, glass blasting and abrasive media tumbling, removes clear anodize as easily as it will colored anodize and the raw aluminum will oxidize, aka "corrode", rapidly.

Re: carburettor cleaning
Sounds like I will have to do more research. The CARBURETOR SHOP had a page on carburetor finishes which said the Carter aluminum was left natural. https://www.thecarburetorshop.com/Carbu ... htm#Carter
Re: carburettor cleaning
Obviously it appears natural aluminum color, would be why that particular anodize treatment is called "clear".

Re: carburettor cleaning
There is an anodizing Company in Houston, I talked to the manager about anodizing my 4100 and 2100 carbs
He asked if they were only aluminum, I told him about the 4 brass tubes ( vacuum for power valve and from power valve to jets )
Did not mention the 4 vent tubes as they would be pulled out
He said there would be an electrical arc between the aluminum and brass tubes and mess up that area so he could not anodize them

Re: carburettor cleaning
Any small parts I clean are put into a 3 quart sonic cleaner.
About 1 cup of white vinegar, fill the rest with water.
I use heat setting. It is just hot enough that I can't hold the parts in my bare hands when done.

Re: carburettor cleaning
I recently bought a small ultrasonic cleaner to try out, primarily for cleaning grungy engine fasteners. What do you guys recommend as a cleaning solution for this? The instructions only say to use an ultrasonic compatible cleaner...
Re: carburettor cleaning
I recently had to clean a pile of engine bolts, nuts, front covers, etc.
I had used a mix of water and Purple Power but it got pretty dirty real fast.
Rather than replenish the expensive solution I added two capsules of my wife's generic laundry detergent.
Bingo!!!
What a difference... now I have been using just the detergent and water on simple cleaning jobs.

Re: carburettor cleaning
Recently ordered a small cheapy ultrasonic cleaner and it's uses have been endless. Definitely worth the money... I think we only spent a few hundred dollars on it. It's a CREWORKS we ordered on Amazon. We run actual aluminum safe ultrasonic cleaner in it and it works great for many things.. I've never put on entire carb in it but we've ran main bodies and bowls through it several times. Works good on steel as well. I've cleaned several sets of rods in it.
