Weak idle to nothin

How old might the oldest fuel be? And I don't mean just what you may have added recently; I mean ANY fuel that might be in the tank.

With the car cold, push the throttle pedal to the floor once and release. Then before starting, go look at the choke butterfly at the top of the throat to see if it is closed. it should be closed when the engine is cold even in MA summer weather.

Did it ever start running better this AM after runing for a few minutes?
