In my experience that engine and carb have shown to be as touchy as it can get. Very difficult to clean and rebuild and many times it is cheaper to replaced. Most of the time I’ve found the the main nozzle and jet are plugged or mismatched. Sometimes resizing the main jet helps, but not always. If the unit is only one year old and has done this since new, you might be able to get warranty help, but that will depend on your relationship with your dealer. Many dealers don’t want to deal with the steps needed to properly enter a warranty claim or don’t have a good relationship with their equipments claims department. Most often it is blamed on letting fuel sit in the carb for an extended period of time, which is not a warranty situation. Good Luck
