The Black fuel may well be fuel mixed with oil. The hose going into the air box is supposed to be a vent , but when there is too much oil in the crank case it blows the excess into the air box. I can't be 100% positive as I'm not there , but it could be the fuel going into the cylinder as the shut off is open , then down into the crankcase and finally blowing into the air box.
So if that is what it is doing , it is kinda doing what it is supposed to. Just way overwhelmed due to the fuel pushing past the carb float and all. In fact the oil level might start overflowing when you open the filler hole.
So. Make sure the fuel petcock is off. Then Drain the oil , change the oil filter and refill oil . Don't go over the higher oil mark on the dipstick.
Make sure the gas tank is empty , Then again make sure to turn off the fuel petcock , and then fill the tank with clean gas and a few oz. of "SeaFoam". Open the petcock and try to start it. Let us know how it goes.
There may be a problem to deal with in the carb. but start with the above and we can go from there.
