What condition results from an excessive amount of gasoline in the carburetor?

• A. Vapor Lock
• B. Flooding
• C. Lean Condition
• D. Rich Condition

Answer: (B)

Flooding happens when the carburetor holds or delivers more fuel than the engine can burn. If the float level is too high or the needle valve sticks open, fuel overfills the float chamber and runs into the throat and into the intake. The engine then receives an excessive fuel-to-air ratio, making starting hard, idling rough, and often producing a strong gasoline smell with possibly wet spark plugs or black smoke. This is different from vapor lock, which involves fuel vapor blocking flow in hot lines; lean and rich conditions describe overall mixture balance, not necessarily a flooded carburetor. In short, an excess of gasoline in the carburetor directly leads to flooding.
