If you look at the carb parts diagram you will see there is 3 different carbs. The carb name is written on the parts diagram illustrations and they are stamped on the carb itself. You will need to look at your carb to determine which carb you have.
This one was the RuiXing carb.

This unit also leaking fuel out of the air intake of the carb. That means the float is not operating properly or the seat valve is worn or cracked. I cleaned the float and the need seat valve and it seems to have stopped the leak. If it it starts leaking again I will replace the float and the needle seat valve. Too much grime on the float can keep it from floating all the way up to seal the bowl from taking in more fuel and and build up on the needle seat valve can prevent it from seating properly in the carb so fuel will leak through the drain from the fuel line into the carb.

Once you take the jets out you can should also use micro drill bits to clean them out. Find the bit that barely doesn’t fit and turn it by hand through each of the jet holes. Then let them soak overnight. The top and bottom of the jets will likely have build up as well. You can use those bots to scrape the gunk off those as well.
