if I connect the breather tube to air cleaner it sucks the oil instantly fouling the plugs to no start if it did start it would definetly be very blue

If that were true then you would have a lot of oil already pooled somewhere; either in the cylinder, or in the intake; and if that were true then either the intake is pulling oil up from the valley or you have a serious mechanical problem inside the chamber.

Are you 100% sure that what you are seeing on the plugs is oil?
