Carb cleaner isn’t the best choice. You’ll get better results with engine starting spray, or dribble a few tablespoons of gas down the throat of the carb just prior to cranking the engine.

Starting fluid can do major damage, sometimes they fire so good the piston keeps going down.
dripping gas into carb can flame back at you & fuel container you are dripping from. Have seen both of these things happen. I have been using spray choke cleaner all my professional life, never seen a issue.
