Banshee won't idle
 

Ok, I have an o2 banshee and it rode fine, rode it all day, 2 weeks later filled it up with fresh gas, mixed synthetic amsoil 50:1, and now the thing won't idle. Drained the gas and tried another 50:1 mixture, checked the plugs and they look good. Still soon as you take your thumb off the throttle it kills.

I don't have a manual and i'm trying to figure out these carbs. There are 2 electrical connectors coming out of the front of the ATV that are just hanging under the gas tank. There are 2 empty holes in the top of the the mechanisms where the throttle cables go in. They have been plugged with some sort of melted rubber. However, there is no idle screw drilled in the side of the carb like on my blaster that has the tors eliminator kit.

My questions are: Does this have an eliminator kit on it because there is no electrical wires going to the carbs? Also, How do I adjust the idle on these carbs? Are they stock?
