Carb and Divorced Choke issue

If you have a raw gas smell, you have a leak somewhere. Check all your hoses, lines and connections from tank to carb. If the carb is flooding, it could leak out the throttle shaft to the outside and cause the smell too. A rich exhaust smell is almost always a carb problem. In rare cases it could be a fuel pump with too much pressure or bad combustion due to a ignition/timing/plug problem.
