1 Faulty Float Valve
The float valve is responsible for controlling the flow of gasoline into the carburetor If the valve is blocked or worn out it might fail to shut off the fuel flow resulting to flooding

Over time debris and old gasoline can block the jets in the carburetor producing an imbalance in the fuel-air combination This can lead to excessive gasoline entering the system
3 Worn or Damaged Float Needle
The float needle which operates in tandem with the float valve might wear out or get broken When this happens it may not seat properly enabling gasoline to seep into the carburetor
4 Overfilled Fuel Tank or Leaking Petcock
If the gasoline tank is overfilled or the petcock (fuel valve) is faulty surplus fuel might flow into the carburetor even while the engine is off

Improper adjustment of the carburetor screws or settings might produce an imbalance in the air-fuel combination resulting to flooding
