The black smoke indicates it was running too rich (too much gas / not enough air.) Make sure the air filter is clear and remove one of the spark plugs (after trying to start it) and see if it is wet. There may be a problem with the float in the carb allowing too much gas to enter the engine Also, if the plugs have been filed (as a result of too much gas) you may need to replace them. Are you sure the wires are on correctly? As far as the noises you were hearing, it sounds like the belts and a very low idle. Has anyone checked the catylatic converter to see if it is plugged?
Try something. Disconnect the fuel line so no fuel can get to the carb. Disconnect it before the fuel pump so no fuel gets pumped. If you have flames coming from the carb, be careful and have a fire extinguisher near by for oil and gas fires. The reason I want you to try this is so the carb isn't dumping fuel. If it doesn't get the fuel to dump, I am anxious to see if the car will start until the carb is empty. Once empty, (follow the directions on the can) but try to see if it will start with starting fluid for a few seconds.
Also, if you don't want to do that, disconnect the power to the coil so the engine doesn't get spark. Then crank the engine and watch down the car to see if it is dumping fuel. When you say you need to hold your foot to the floor for it to start, that tells me it needs the air to burn the extra fuel.
Please be careful doing this. I don't want you to have a fire and based on your description, it is possible.
Let me know what you find. I feel confident that the carb is the problem. It may need rebuilt, have a bad needle valve not stopping fuel, or a bad float.
