Idles fine / Only runs when choked

I have searched and found no answers. I have a 2003 sportsman 700 HO. Hereís my problem: 2 weeks ago I was using my machine to put in some food plots. I was working it real hard all day. Late in the day, it started running bad. It would back fire and hesitate. If I choked it a little bit, it would run fine. It still would idle normal and I didnít have any problems starting it. I brought it home and this is what Iíve done so far. I changed plugs and installed a new fuel filter and new gas. I cleaned the carb (using carb cleaner, I didnít disassemble the carb). I also replaced the carb boot. I starts and idles fine. When I give it gas it almost dies, but if I choke it a little bit, all is fine.
What could be causing the problem? Should I rebuild the carb? Thanks in advance

it still sounds like you may have some dirt in the carb.yet. try cleaning the pilot jet,normally they are right beside the main jet, just remove it with a screwdriver ,spray some carb.cleaner thru it and some compressed air and all is good.
