Quad not running smoothly...

I recently moved my ATV from Pennsylvania (low elevation) to Denver (high elevation). As soon as I took it off the truck, it wouldn't stay running. It runs if I give it a little gas, but as soon as I let off the throttle, it stalls out and dies. It ran fine in PA. Think it could be because of the thinner air? Where do I start with fixing it?

Thanks!

      Suzuki king quad 300 idles great but Boggs when you apply throttle
      By 97kingquad
      Okay so I bought this 1997 sazuki king quad from a guy and he had it for a few years. 
      He had it registered and on the trails last year but he said it bogged and backfired when he would try to drive it. so it sat for a year. 
      I bought it for 800 bucks and got it running that night and it ran great for a few days 
      But I parked it the other night and went to start it again and it was really hard to fire up and when I did it was bogging and idling high then low again.
      So I took the carb out and cleaned it (ended up doing it twice because it was still doing the same thing) 
      Now today I have it running slightly better, but it is still like 20% 
      I have been looking it up and trying to figure it out but I can't find the issue, has anyone else had this problem? I'll attach a video of it running and giving some throttle

      Help! Polaris 2001 325 Magnum Not Running
      By PupATV
      Hey guys! I am new here to the forum and need some help getting my Polaris 325 Magnum 2001 Running.....So I got it for free and it has never run quite right...I put a aftermarket carb on it last year and it was running fine but it only went like 20 maybe 25mph max......But then the needle and seat sealed leaked within a yeah and it flooded it REALLY bad so I changed the oil because it was full of gas. So then I put a genuine Polaris carb on it and I have it set to all the factory specs, but it was still not running right....So I replaced the ignition coil and the spark plug and that solved one of the problems I had (It would bog down and stop running when i would go up a hill) But it still didn't have that much "Punch" to it like my Kawasaki Prairie 300 ans Suzuki Kingkuad 300.....So I replaced the CDI but it's still not running right! It's acting like it rich kinda....So it runs mostly okayish when I have the airfilter on but the top of the airbox off but as soon as I put the airbox lid on it like REALLY bogs down and wants to stall really bad. I have the carb at the factory specs and it has a pretty new fuel pump so I have no ideas whats going wrong! It still nly has a top speed of only about 30-35mph and it sounds like it's choking the whole time! Thank you for sticking to the end, and I hope you guys can help me!

      By bhristianzx12
      I have acquired a free 92 Polaris 350L 4X4. Ive replaced carburetor from ebay, replaced spark plug, im trying to pull start but sounds like it doesnt want to fire. Spark is a bright orange spark (checked with spark plug tester), replaced plug, pre mixed gas from an external gravity feed tank. Compression test good. Anyone got any recommendations for me?
