Rhino 250 Bogging

[GillyGang]

Ok....here goes. Brand new model. During idle and giving it a little bit of throttle it makes a whooshing sound from the new designed air filter. Every 5th or so tiny rev of the throttle it will stall. Like it chokes out. When riding it bogs(usually at the top of the gear or at full throttle). It seems like there is only a idle screw on this carb. I checked for leaks and it seems ok. Attached are some photos.
