2BBL or 4BBL? It makes a difference. The 2BBL will have a hollow brass float, the 4BBL (if stock) will be a QuadraJet and will (most likely) have a composition float. There are different things that can happen based on which one you have. It has already been pointed out that you shouldn't push the pedal all the way to the floor when hot. I doubt that there is any bleed down from the needle and seat, or percolation after you shut it off, based, as you said, on the fact that it starts cold. If the bowl was empty, it would still crank for a bit before it started, cold.

Have you always had this problem? If it is a recent occurrence, Think about what has changed from when it did work properly.
