Aerosol? Engine degrease?
David, what happened to the good old days when you boiled a carb on the kitchen stove when your wife was gone to a meeting...Then sprayed air freshner and lit candles to cover the smell.??????Yeah
Gallon can at NAPA or other parts stores.
Clean most of the crap off with carb cleaner and a blow job.
Then dis assemble and soak overnight or longer in the cleaner solution.
Another spray and blow job and that's it, unless you want to beautify it some.
