stalls at stop after driving

[freak]

My 1930 A is new to me so I don't have any drivability history but here is my problem. After a drive of about 15 or so miles, occasionally when I pull up to a stop my engine will die. I can restart but takes it a little bit of cranking. During cranking I don't do anything other than set the spark retarded. It seems to me that it may be running rich and getting itself flooded out because I usually smell gas but don't know for sure that is it. I know this is all vague but if anyone has any ideas I would appreciate it.
