Fuel leak from air intake

My push mower with 5.75 B&S Quantum engine (Model no. 12H802) runs fine but is dribbling fuel out the carburator air intake and down through the air filter assembly. This happens at a pretty good rate - you can see it flowing out the intake and about one large drip per second comes from the bottom of the air filter when the engine is off. Fuel also sometimes squirts from the bulb when pressed. I also notice that when the bulb is pressed and the air filter is off, the fuel squirts toward the air filter - don't know if this is normal, but it seems like it should go the other way. Don't know how to disassemble this carb. Any ideas?

Sounds like you have a float problem. Carb needs to come apart.
