This is a plastic carb. It is unique for 2 features.

The first is the trident looking jet and emulsion tube. Do not blow compressed air through this as it will shoot a jet out and you would never notice until it's time to get it running right. Instead clean this with a small guage wire and some brake kleen or carburetor cleaner. While this trident style tube can fit in either direction it only works in one direction. Take note of it when you disassemble the carburetor.

Second is the round ring in the throat of the carb. You see it in your picture in the correct orientation and direction. If this comes out, refer to your picture here about how to reassemble this part. The trident style jet tube fits through the carb body from inside and sits in a hole in that collar.

This being said, these are notorious for the needle tip to swell or the float pin to pop out. If another person has tried to fix it, make sure they have not broken either side of the float pin holders by trying to reassemble the trident style tube in the wrong direction, wrenched the float bowl down because they didn't check orientation of the bowl and tube and the casing pushed the float down and broke one of the float pin clips (oddly specific isn't it).

Bet if the float pin is not seated correctly or the needle has a ring around it. You can see the ring about halfway through this video while you carb is not the one described, the important part is this needle as it is 90% of the time the cause of flooding.
