Husqvarna 570 oil in carb

[cunhab52]

I replaced the cylinder and piston on my Husqvarna 570. Now when I run it, there is oil being pulled in to the inside of the air filter through the carb. The only things that go into the carb are the fuel line and the small line that comes off the cylinder. I can't figure out where the oil is coming from. Chail oiler hose is not leaking and the chain is being lubed.

Aside from the oil, how does it run?
