Thank you for your question.
We know the carburetor was the cause of the problem because now it starts. Even though you have cleaned the carburetor, I suspect it is still the cause of the problem. There are small passages in the carburetor that can be difficult to get too. You can try to clean the carburetor again and see if it helps. I recommend getting a carburetor cleaner that you soak the parts in. just make sure you remove all of the plastic and rubber parts before soaking it. While the carburetor is soaking, clean the rest of the parts with carb cleaner. After letting, the carburetor soak for a few hours remove it and blow out all of the holes with compressed air. If the engine still hunts when running see how it does in snow. Some engines will hunt until it is under a load. If it does the same thing, I recommend replacing the carburetor.
Please let me know if you need further assistance.
