carb diagnosis
I'm not familiar with diagnosing carburation, or anything for that matter, but i like to learn by doing. So when my quad dies going downhill at idle it gives me a reason to tear it apart and learn. It idles a bit rough and also a bit cold blooded on start up, but revs good. On another note I have a stage 2 dyno jet kit and plan on upgrading from a modded airbox to a open setup(sixsixT or Prodesign). I only run on dunes at the oregon coast and was wondering what would be the best setup for my riding and if setting up my jetting would eliminate my dying downhiller.

The running rough, dies pointed downhill and cold blooded...al point to a lean condition. I agree with checking the float level, it may be too low. Also check for intake leaks.
Be aware if you take the air box lid off, itll lean things even more.
You could try redoing the mixture screw adjustment, and make it slightly more rich. If you get to 4 turns out from lightly seated, and its still not enough...youll need to go bigger on the pilot jet.
Heres a good article on jetting and carb dianosing.
