Found oil in my intake

[Alrmanjacoby]

I have been trying to tune my nibbi pwk but no matter how I jet it I always have an issue with it dying when I launch the throttle. I pulled my carb off to make sure I didn’t have any air leaks anywhere and I noticed oil in my intake manifold. I have no air leaks anywhere and I’m not sure if the oil issue is related to the carb having troubles or not.

Only things I can think of is the valves set too tight and therefore not completely closing, or you have too much oil in the engine. In your picture, it looks like a clone or predator engine. You didn't say what it is. If it is either, the valves need to be at .003" (I am assuming you know how to properly set the exhaust ) and when COMPLETELY empty add no more than 16oz. of oil.
BTW, what does launching the throttle mean? Are you saying that when you open the throttle, like giving it full throttle?
Well really bad valve guides, or really worn out rings could also contribute to that. Do you know how old the engine is? Does it seem like it's really worn out, or is it still sort of fresh?
