My neighbor puts carb stuff in a small container of gasoline (with a
lid) then sets that container in an ultrasonic with another liquid
(forget what he uses , maybe water?) . He says gas works better than
most "cleaning solutions" but he doesn't want the gunk in his cleaner -
or the possibility of a rapid deflagration . I have added him to my
(very short) list of people who are allowed to work on my stuff .

A tip I read about cleaning carbs was putting them in an ultrasonic
cleaner as a whole unit. Thought to myself it would be a good excuse
for getting one (ultrasonic) and then I'd further investigate what to
use in the tank for good results. I've torn down, cleaned a few carbs
in my day but would love a different method that works well😉 Just a bit
of info<shrug>

Ammonia, but it can be too aggressive to the metal as well. I lost a car radiator to/from sitting open in a horse stable while I was getting the
head repaired after the timing belt broke. Now I change the belts on
schedule religiously (on my knees).
I haven't tried this: https://blog.thepipingmart.com/metals/how-to-remove-corrosion-from-brass-fittings/
Vinegar plus Dawn slowly attacks soap scum in the shower.
The carb crud problem I see is a clear gel that dries to a white powder. Supposedly it is aluminum hydroxide dissolved from the castings with the
help of ethanol and water.

Vinegar would be a better bet or a condiment containing it. A woman I
know swears by tomato ketchup for cleaning her horse brasses.

Maybe I'd try this outside while watching with a CO2 extinguisher in
hand. Pretty sure it would be a last resort, Hail-Mary kinda thing
though...
I've wanted an ultrasonic cleaner to experiment with for years. Stories
I hear sound too-good-to-be-true...

Ammonia, but it can be too aggressive to the metal as well.Not sure about the ammonia suggestion as it attacks the zinc in brass

I'm starting to renew my interest fishing although I will probably never again be a go-fast hard charging local tournament fixture. I have had a
new fishing buddy (a few years now) kind of reignite my interest in
fishing if not all the other stuff associated. I'm trying to keep it
simple. Mostly we have been fishing out of his boat, because I mostly
didn't go if I wasn't invited. Since I've been getting back into it
there have been a few times I wanted to go when he couldn't. A few of
those times I went... and my boat ran like crap or hardly at all. A year
or so ago I pulled the carbs, find some minor restrictions, cleaned them
up and it ran a little better for maybe one trip. Mostly I was still
fishing out of my buddy's boat so I left it sit. Its pretty funny. I
took him out a few years ago, and shortly after he bought a boat. The
other day I made some baits with him in my back shop and yesterday he
showed me all the new tackle making stuff he bought. He goes all in. I
had to laugh when he opened his cabin to show me his first plastic
purchase was ten gallons. When I first started (a long time ago) I think
my first plastic purchases was a single pint.
A month or so I got out in my boat (The Tin Can) and it wouldn't run
past an idle. It would go in gear and idle just fine, but any throttle
and it sounded like crap and died. I figured it was a fuel issue because
if I bumped the choke it would speed up and keep running. A week or so
ago I pulled the carbs and discovered all the brass pickup tubes were
green. One was plugged solid. I had to make an extended d drill out of a piece of wire to clear it from the top of the carb. I didn't really
think about it, but after cleaning all the passages the carbs seemed to
work just like they should. Nothing was sticky. Without thinking i
slapped the carbs back on, put a cuff on it and ran it on the hose. It
seemed to run okay at idle and with some throttle, but it was surging a little. I hoped a few runs on the lake would clear it up as so often
works. Not this time. On the water it was hard to start, and would
barely run in gear. Sigh.
Okay I'm slow. Or perhaps overly hopeful. The clue I obliviously ignored
was that all the pickup tubes were green. A little water isn't going to
turn brass green. They had to be sitting in water for a while for that
to happen.

So... I'm going to pull the carbs again to drain and dry them. I don't
want to dump the fuel in the bowl into the engine cowling, and I can
barely reach the drain on the bottom carb anyway. I was debating the
best way to drain the tank when I remember I have a 6 gallon tote tank
around somewhere I can use to test on good fresh gas. If it runs okay I
can pretty much diagnose its bad/wet gas.
I'm curious if there is a way to "easily" remove ALL the green copper corrosion of the brass, or if I need to just do it with tiny fine abrasives/polishers by hand and plan to spend an afternoon doing it?
I'd also like to know if there is anything else I should look for as a
result of running wet gas through the engine?
Is it worth the bother to buy some Heet or should I just dump the gas in
the tank and get rid of it?
(I still go fishing when the outboard doesn't run well. I just use the electric and stay relatively close (mile or so) to the launch.)

Cleaning carburetors is sooooo much fun. As I was cleaning number 2, I realized I never cleaned "this passage" on number 1, so it comes back
apart again.
It must be fun. This is the third time I've been inside number 1 TODAY.
By the time I finish #3 I might figure out everything I need to clean
and degunk.

 My neighbor does some small engine repair/tune-up . He uses a small container of gasoline submerged in water in his ultrasonic unit to clean
carb parts . He's got one of my chain saws right now for a carb kit
