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.
Put a brass fitting in your Ultrasonic Cleaner with some Pinesol and Distilled water. Run a couple 15 minute wash cycles on it with the solution up to temp.
Might have to help it along with a fine stainless steel wire brush after the first wash cycle to help clean off any gasket sealer or pipe dope. But that brass fitting should clean up like a shiny new one if your cleaner is working properly.
That would be a good test. Cleans up Brass carb floats nice too.
