James summed it up nicely. I would like to add to the subject matter discussion. I am very pleased with my ultrasonic cleaner from Vevor, and go big on size as James stated. The results are in the secret sauce not the ultrasonic cleaner. For me 2/3 Simple Green (water-base) and 1/3 pre-heated water worked for me on a set of J2 carbs. Acetone and other solvents work great but remember ultrasonic cleaners are not explosion proof and acetone has the lowest flash point of any solvent available to the general public.

Subject: Re: {Chrysler 300} Ultrasonic Cleaners
I've been using one sourced from e-bay, for
about 4 years now for carburetor rebuilds with excellent
results. I still manually remove all the caked-on crud beforehand,
and spray & blow all orifices with carb cleaner afterward. I use
cheap cleaning vinager as an agent. I have soaked
completely rusted up metal pieces in the vinegar bath for a few
days, then run the machine for a couple of cycles to have the parts
come out with clean metal. Get a machine with as big a vat as you
can. If you're doing old style pot metal carbs with the bronze
coating such as a Stromberg 97, don't let them in there too long,
or use a milder cleaning agent.
