I would start with checking out the cold start valve and associated system parts for correct operation. This could involve using a pressure gauge for a more in depth analysis. It could also be that the engine is just set way too rich, what is your gas mileage? You could also have bad ignition wires, worn spark plugs, vacuum leaks, etc. Depending on how much care the car has had will determine were to start. If you have never done a tune-up and the car has some mileage on it now might be a good time. The gas smell could even be a fuel leak which you would only notice when the motor is running or right after you shut down. Typically a car could sit for months and as long as the battery is charged up it should start right up with maybe a small puff of smoke and a smell until the cat heats up.
