Fuel in the oil....

Nope,Holley remanufactured Mikuni carb.$$$ Biatch to remove the top & get it & the choke linkage back together properly. A while back the needle & seat were hanging up. I wonder if that could let enough fuel past to cause this. I mean, there is a lot of fuel getting in the oil. Maybe I should put a regulator on there & set it at 4 lbs or so.....
