I have the same thing happen in my '38 blown Chevy. What you experience isn't true dieseling which is the result of carbon build up. What you have is your idle set to high and gas continuing to be forced into the combustion chambers at a rate faster than your engine can burn it up when you turn off the ignition. When I reset my idle below 700 rpm's it doesn't happen, above that it does, easy as that.
