The smell of rotten egg is coming from your catalytic converter that is plugged up White smoke is an indication of water (usually antifreeze) in the exhaust.
Are you sure it's Gas and not Water. I find it hard to believe that gas made it past your Catalytic converter and the muffle. Good Luck and Remember.Change Your Mind, Not Your Oil.Use the First In Synthetic Motor Oil's.See My Bio For Information & Contact Details.

Start the engine. The water will evaporate from the heat generated by the engine.
It may or may not have damaged the converter. Remove the water and then you will see. More than likely it will be fine.
Catalytic converters are but one part of a comprehensive pollution control system on a vehicle. Catalytic converters are 100% effective in achieving the pollution reductions demanded of them by the auto manufacturers. The converter is the last step in cleaning exhaust before comes out the tailpipe and into the air. A catalytic converter contains a catalyst. A catalyst acts as a chemically neutral facilitator of molecular reaction between other chemicals, without the reacting chemicals or the reaction byproducts effecting the catalyst itself. The whole purpose of the catalytic converter is to convert exhaust gas pollutants to environmental friendly chemicals and compounds that exit through the tail pipe at the rear of your vehicle. In a typical gasoline-powered passenger car, the target exhaust gases CO2 and water. Ever see water dripping from a car's exhaust pipe? That's not a defect. Dripping water from an exhaust pipe means that the car's pollution control system - and its catalytic converter - are working properly.
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
No, water coming from the exhaust is normal in small amounts. The temp differences causes condensation. When the car sits, the exhaust is cold or ambiant temp. When the vehicle starts, the exhaust system warms up, causing condensation. There are actually weep holes in most mufflers to let the water out to prevent rust.

This may likely mean that there is water inside your engine, and the most likely culprit is from a blown head gasket allowing it to leak inside. Check your coolant level and see if it is lower. Moreover, try to limit how much you are driving the car- as coolant in the tailpipe will destroy your catalytic converter.
You repair a clogged catalytic converter by replacing it. A catalytic converter works by having unburned gasoline or some other substance touch a metallic catalyst such as platinum or rhodium. When the catalytic metal becomes covered over with garbage it stops working. When it stops converting the garbage to carbon dioxide and water, the small holes in it then become clogged. Then it will not let exhaust gasses pass though. No way exists to clean out a catalytic converter. They can only be taken apart and the substance used as raw material to create a new metallic catalyst. You can drive fast and blow the dirt off!
Convert unburnt fuel, carbon monoxide, and nitrogen oxides into nitrogen, water, and carbon dioxide.
