My BIL took in an 8hp shredder to have it fixed, as it had sat for a couple
of years. The mechanic said that "the carburetor was so gummed up, he had
to replace it." And he did kindly with a USED one, which he charged $125
for including labor. I believe I could have soaked and brushed it into
usability.

Replacing the carburetor is common practice in my experience.
Cleaning an old one is labor intensive and there is some risk that it
may take more than one cleaning/rebuilding to get it right. That's OK
if you are doing the work yourself and have lots of spare time but the
guys making a living at it like to turn the work around quickly and
get it right the first time.

The EPA may have also banned the chemical they used in the carb "hot
tank". Back in the olden days a few hours in a hot tank would make
them look like brand new and all the varnish, gum or whatever was
gone. Blow it out with a little shop air, put a "kit" in it and you
were good to go.

The hot tank I know about is lye and is used by engine rebuilders to
soak the engine blocks and other parts. It will dissolve many non
ferrous metals, especially aluminum. I use the same stuff to dissolve
aluminum to make hydrogen for the UFO balloons. The stuff used for
carbs is similar to many paint removers, except it is not a gel.
Smells similar. Maybe methylene chloride, but I don't really know.
Used at room temperature. Some evil ****, whatever it is.

You put the stuff in dry cleaning bags. About 1.2 oz of lift per cubic
foot. A one cell mag lite bulb, like the keychains size uses. Looks
like a grain of wheat with two wires sticking out. AAA Cell.three
inches of very light wire. It will look like a satellite, in the
unlikely event anyone notices.
