My thought is always to have extras if I can. If the carb fits then clean it and keep it handy. Then when it comes time to clean the carb on the scoot now. You can just swap them and scoot is good to go without down time and you can clean the carb you take off at your leisure and then have it ready for the next time when you need to do a carb clean and just keep rotating them out.
EXAMPLE: I do this same thing with our Wii and rechargable batteries. I have extra so a set or two are always charging/charged and when the ones in the remote die I swap them out and there is no down time for kids or ourselves if we are in middle of a game.
