Carb cleaner

[Reckless]

 Spray carb cleaner. Besides taking the air cleaner off is there another way of getting into the carbs? Is there some kind of fuel line adapter that can be installed in the line? Spraying it into the throat of the carbs it doesn't get into the bowls. I thought I saw something for this somewhere but can't remember what it is called. Or maybe I was dreaming!
