If you have a carb, and nothing but a carb, you probably need to have your carb adjusted. If your carb has an automatic choke, it could be stuck. Check and make sure the choke's butterfly valve (the one in the top of the carb) is opening up once your engine has warmed up. If it doesn't, disconnect the valve from the auto choke and manually open it, that should change idle. Do not drive with the choke disconnected. Write me back if that doesnt solve the problem.

The big red wire on the big connector on the firewall is the problem. You need to take it apart and clean the contacts. Another fix is to run the big red wire through the connector after you solder it together.

Well as to what you'r describing above, if there is indeed black smoke and raw fuel smell then you vehicle is running rich. That means that insead of having the perfect 14.7 mixture of fuel and air, your engine is burning more fuel then air. The problem is most likely fuel related so if you know enough about cars you can check these areas. First you may want to revise the spark plugs, just to be sure they are sparking enough for a complete combustion. Next the injectors may be clogged up, one of them or a couple. Try removing one of them and taking a look at the spary tip, if very dirty clean it and do the same for the rest. Another possible cause may be sensors as well, Air Mass, Oxygen sensor, Mass Air Flow. Depending on the make of vehicle, sensor location and name may change especially for lexus. The Air Mass Sensor is in charge of calculating how much air is into the engine so that the computer can determine how much fuel to use for combustion. Having that said if the sensor because faulty or dirty with carbon then it can cause the vehicle to burn fuel at different levels for the reason that it may not be accurately reading how much air is entering the engine. My advice would be to take it to a local repair shop for a diagnostic and have them determine what the problem is and if you might be able to fix it yourself to save some time and money.
Hope this Helps!
