Unhappy Walbro 5-4993

I have a B&S 16.5cc engine with a Walbro 5-4993 carburetor. When I put fuel in, and try to start the engine, fuel comes out the carburetor and won't stop until I pinch of the fuel line.
Would rebuilding the carb fix the problem?? Or, what will??

Yes rebuild the carb you will need the engine numbers Model, Type, & Code to get the correct parts. Might need a new float too.

The floats stuck or not sealing.
May get away with just completely taking it apart and cleaning with carburetor cleaner.
Shake the float while it's out to see if it's leaking.
