    Just curious where the flapper should be resting at with the engine off? Is there supposed to be a gap? I don't know the technical term for the flapper...choke valve?

    It should be just how it was when you shut it off. If you were driving an it was completely warmed up and open, unless you pump the throttle to set it, it should be where it was when last running. At operating temp it should be wide open.

    Choke plate.

    If the engine is warm when shut off the choke plate should be perfectly vertical (open).

    When the engine is cold and hasn't been running (say more than 6 hours) it should still be vertical as when shut off, pending the choke being set either by pumping the gas pedal (thermospring method) or by the automatic electric choke. Once activated the choke plate should be roughly 1/8" from being completely closed.
