What's a good 'cleaner' to clean my carb?

Super Tech (Walmart Brand) is best I have used
Do you mean "Super Clean"? I have used that to remove the faded coating on my plastic dash pieces (soak a few days). Would probably work on a carb. I would use carb cleaner only to spray down the throat. If you spray outside, I think it can eat up the rubber diaphragm in the choke pull-off.
