Carb needs a new inlet valve seat seal. (this is what closes & shuts off the fuel feed to the float bowl, when the float reaches it's up position)
This condition may not be so great for your engine. If raw fuel pours into the cylinders, it will wash the protective oil coating from the cylinder walls.
This will cause premature ring wear & oil dilution. Gasoline is a solvent of oil.
