OK, I'm not the first person on the list to call about fixing small engines but it sounds like a gummed up carb from just sitting for a long time. The correct fix is to remove the carb and take it apart and clean the guts real good. However, I overhauled a one barrel carb on my car, once, and I'll never do it again. I didn't know what I was doing and I didn't have any money to pay someone so I took it apart, cleaned everything with gasoline in my living room, and then put a carb rebuild kit in it and reinstalled it and it actually worked. Today, I would remove the carb and soak the whole thing in carb cleaner for 24 hours and clean up what I could, shake out as much carb cleaner as possible and reinstall it and hope like Hell that it worked. One of the other preppers probably can help you better than I can.
