Seems like my Yamaha '00 800 XL Waverunner (2 stroke) is starved for air. I am guessing air filter or choke cable. Any other places to look?

Update: I pulled the intake silencer cover off and the case has oil in the bottom of it. Where did that come from??

Found the problem, zero compression in #2 cylinder. Ya, that will make it run funny. Here comes the wrenches.
