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

I dont remember the brand names on the part soaks. Due to epa regulations they may not even be available today. The one gallon isn't large enough for anything other than the smaller parts. The 2 or 2.5 gallon soak will take a 4 barrel carb. 1 gallon comes with a basket. Larger basket is/was sold seperately. None are/were cheap.
Those would make a carb look nearly new. If aresol cleaning is all you need, Advance auto parts had a brake cleaner at buy one get one free = 2 bucks per can. It will clear small passages, etc..
