Valves mate!
Most of your description points to a valve clearance problem on the affected cylinder, have you done a compression test?

Sean,

Please tell all you know about it, like the exhaust system, intake system, ignition, etc. Older bikes are seldom stock after so many years.

So what work have you done so far to get her running?

When you say it's running on 3 cylinders, can you tell me how you know for sure? You can be certain by getting her running, and spraying water on the exhaust headers. Water will turn to steam on a working cylinder, but just run down the pipe on a dead cylinder. Remember when running your engine to have a small fan blowing across the fins, you don''t want to aggravate anything by overheating her.

The first things I would do are drain the old oil and use some fresh 10-40 with a new oil filter. Then totally drain out the old gas, remove the rust from the tank, then add an inline fuel filter. It's possible some rust or crud has blocked the jets in that carb, keeping the cylinder from getting fuel. Or it could be a bad piece of the ignition sytem on that cylinder. Maybe a bad spark plug, or bad plug cap, or the plug wire is corroded in the cap or at the coil end.

Did you clean the carbs at all yet?

The smoke may be from the rings sitting so long they are stuck and not sealing well. Or dried up valve stem seals. Or maybe you added oil to the cylinders to free things up??

Let us know.

Too much oil is just as bad as too little. There is a sight glass on the lower right side of the engine. Proper level is between the two marks next to the glass.
