Spray a little carb cleaner directly into the spark plug hole and then see if you can get the engine to fire. We need to see if the problem is in the fuel or mechanical system. At that point we can tell you how to proceed.
Wouldn’t be the first time we’ve seen on this forum that being penny wise and pound foolish has cost people money. I could be wrong but the majority of the non OEM carbs out there are piles of junk and you get what you pay for.
