What do you guys use to clean the stubborn stains from the exterior carb body? You can see in the pic that I used rust remover (phosphoric acid/corrosive) to clean the parts that will not be effected by air and fuel flow. It does an excellent job. Leaves a nice, clean matte finish. But I didn't want to dip the entire body into this elixir because of the sensitive nature of the restrictive jet holes. Have any of you used rust remover on carbs? Or are there better solutions? Thx.

There is carb cleaner that comes in a gallon can. Napa brand, I believe. Soak it for awhile.


Cheers!

Try using an ultrasonic cleaner.
Works wonders!

Tape up the jet holes and soda blast! Guaranteed to work. Just be very careful to only hit the exterior and clean it up well afterwards.

When I bead blasted my A50's barrels... I thought I did a good job with taping everything. When I removed the tape, the whole insides (cam followers included) were covered glass beads. It looked like a sugar doughnut. Spent a long time with WD-40 and compressed air, but eventually got all the beads out!

Nothing works like media blasting smile

Methylated spirits will get rid of that as good as anything and will be cheaper than anything else you can get your hands on.

Boiling is my favourite method.
Big pot of boiling water on the BBQ outside ( unless you enjoy eating cold baked beans & sleeping on the couch ) .
Pop several of those dishwasher tablets ( the ones with the ball in the middle ) in the water & toss the carb in.
About 20 minutes of a nice rolling boil with have it quite clean with a grey coating of zinc hydroxide which will rub off to a nice polished finish.
Pull the carb out of the boiling solution then pop it into a pot of clean boiling water and allow it to cool down before a final rinse in cold water

Just shoot carb cleaner on it or soak it in laquer thinner, just don't git any on plastic parts. Carb cleaner in a spray can does wonders on aluminum and WD40 does a nice job on the oxidized aluminum.

Once I needed to heat up a right half of a case to get the right main bush out and stuffed it in the oven while momma was gone. I got the bush out, but the house stunk with the oil that had burned during the heating process that was in the case that I couldn't srub out ahead of time... wifey came home to a house full of smoke... there was no hiding that!

I painted a gas tank fer a guy once then to do a quick cure i baked it in the oven. You couldn't git the smell of paint fumes out of that oven or the house. Luckily I wasn't married and was renting at the time.

Dont forget that very often you are judging the effectiveness of the cleaning process by looking at it on the outside.
Using solvents alone can often give a clean exterior but leave crud in the internals. May look good but still leave you a problem in the internal passages of the carb (more likely with the crap starvation fuel we get nowadays).
Whereas by the nature of the process the ultrasonic cleaners clean inside and outside.
So IMHO and IME I prefer to clean carbs ultrasonically.
But---hey---they tell me its a free country ---so up to you.

I use ultrasonic cleaning too for my carbs, although, if the idle jet is clogged, ultrasonic cleaning will not always remove the blockage.

Thanks for your excellent advise. As it turns out I did use a diluted (1:1) solution of rust remover/water. Worked a treat.
