Wait, if all cylinders show the same amount of "oil", then it could exactly be an intake manifold sealing problem. I'm thinking, is it oil or gas you are seeing in those cylinders? Probably oil IMO unless you work fast. :)

IMO, your plugs read way rich. I think you have oil intrusion into cylinders. Carb may be rich as well.

Or... I could be wrong. :)

Well when it was running the smoke coming out of the breather was extremely toxic. Smealt like a lot of burnt fuel vapors to the point it was burning my eyes. So I still feel the fuel is the biggest issue at the moment. I also had a small oil leak that I had to fix and when I wiped it with my finger it smelt like a lot of fuel in the oil.
