That hole is not for fuel flow. It is for a vacuum pulse from the engine to actuate a diaphragm inside the carburetor. There better be a matching hole in the insulator block that goes in between the engine and carburetor, and the associated intake gaskets. The diaphragm acts like a fuel pump and recirculates the fuel from the tank through the inlet hose, through the fuel passages inside the carburetor and out the return hose back to the fuel tank.
The system will not work unless there is fuel all through it from the get go. That is why there is a primer bulb, to let you prime the system with fuel before trying to start the engine.
If you do get fuel out of that little hole, then you have a torn diaphragm inside the carburetor and the fuel ls leaking through the tear.

masterx1234 your fuel filter may be clogged.
It is located under the carb cover on a wallbro carb .Page 4.
My primer bulb was as hard as a rock until I cleaned the screen.

Check page 4 on the how to.
You also need to return the fuel to the tank .
Run a feed and a return .
Some people just run the feed line.
