Young Harold Finch's father says that the engine is flooding. The part he holds up is the accelerator pump diaphragm. This could not cause flooding. This part causes fuel to squirt into the throttle body when the accelerator is depressed. If anything a torn diaphragm like that would cause a lean condition when starting, not flooding. It would also cause a hesitation. See more »


Arthur Claypool: You know, Harold was the most brilliant of all of us. If anyone was going to change the world, we knew it would be him. You know, what did you end up doing? What's your field of expertise?
Harold Finch: Insurance.
