3.5 hp B&S leaks gas from carburetor when priming

Re: push mower with a B&S 3.5 hp engine, Model: 95902, Type: 3107 01, Code: 96050451

When priming, gas leaks from the carburetor below breather connection. There are two small holes there, obviously by design, both plugged with what look like a tiny stainless balls. The one just below the breather leaks when pushing the primer bulb. When one plugs the hole with a finger, the carburetor can be primed just fine and the engine starts without any problems.

What are those holes for and how to fix the leaking one?

Sounds like you just need a new carb. They are cheap.
