Thanks, I have certainly been called worse.
About the gas, when you shut off the engine you hear the famous Model A sound "shhh uh shhh." That is the sound of the piston coming up on compression and not getting past TDC. Since the piston doesn't go past TDC it reverses and goes back down. While this is occurring the cylinder that was on intake is also reversed and blows intake air past the jets in reverse creating the puddle in the carb. To alleviate this you can anticipate shutting the engine off and turn off the fuel valve before hand. That way the car runs out of gas or nearly so, less or no gas, less or no fumes.
God I love these cars.
