How is a flooded engine, equipped with a float-type carburetor, cleared of excessive fuel?

• A. Crank the engine with the starter or by hand, with the mixture control in cutoff, ignition switch off, and the throttle fully open, until the fuel charge has been cleared
• B. Crank the engine with the mixture rich and ignition on
• C. Crank with the throttle at idle and ignition off
• D. Stop and wait 3 minutes before trying again

Answer: (A)

Flooding is when too much fuel fills the intake and cylinders. To clear a float-type carburetor flood, crank the engine with the mixture control in cutoff, ignition off, and the throttle fully open, using the starter or by hand until the excess fuel is purged. Keeping the mixture in cutoff stops fuel from entering the intake, while wide-open throttle allows maximum air flow to sweep the fuel out of the carb and intake. Cranking with ignition off prevents any spark from igniting vapors during the purge. Once the fuel charge has been cleared, you can restart normally.
