Hello and welcome to Just Answer,

The problem is a plugged up jet in the carburetor. The best thing to do would be to do a complete rebuild of the carburetor. This requires removing the carburetor from the engine, taking it completely apart, and then soaking the parts in a carburetor cleaning solution. If this is not something you want to do at this point then there is something we can try to see if we can get it going. You will need to still partially disassembled the carburetor, but the carburetor does not need to be removed from the engine. The first thing you need to do is turn the fuel off or if it does not have a fuel shutoff valve then use a piar of vise grip pliers and clamp them to the fuel line to stop the fuel flow. You will then need to remove the bolt from the bottom of the carburetor. If possible have someone hold onto the metal bowl part of the carburetor while you remove the bolt to prevent the bowl from coming off. The bolt you take out is the main jet. It will have some small holes in the sides of it as well as one down through the center. Use a small wire and clean out those holes and then blow it out with compressed air if you can. Put the bolt back in it and then try it. If it still does not seem to run right then the carburetor need a complete rebuild. Here is a link to help you. Look at pictures #6 and #7. Let me know if you need anything else.
