New Ultrasonic Cleaner

That's very cool, thanks. I can already tell you with great certainty mine will not do that. I wonder if there is a fix for it? I've often thought about if maybe it had an electrical adjustment inside it somewhere.
I'm not an expert but I think they basically have a control board, amplifier, and transducers. What I would imagine could go wrong during the manufacturing of them is when they epoxy or glue the transducers to the tank they move or skew and don't get full contact making the signal weak. That's not something I know for sure just thinking out loud.
"I am going to bet" that ultrasonic has one serious downfall.......and that is "I bet" that when you get "down into" the tiny bleed/ idle passages, especially on smaller carbs, the ultrasound will do you no good at all..........and that the only thing left is the old fashioned action of aggressive cleaners.

I would love to be proved wrong........I might just buy one.

I wish photobucket was still accessible because I had a lot of high resolution close up picks of carb parts I ran through it. Basically anywhere the liquid touches gets "scrubbed" for lack of a better term. I have ran a couple lawn mower carbs through mine and it did a great job. It doesn't really whisk away dirt and grime as much as detach it from everything and leaves a bare surface. After 30 minutes in the tank a quick rinse and blow through with compressed air leaves everything spotless.

Something that might appeal to your electronics background is they are used to clean circuit boards and electronics with special solutions. I haven't tried that though.
