Hi all. So I recently got a 97 sportsman 500. I had it running good. My daughter and I were ripping up the back yard with it. So finally had a day to go riding. Got to my buddy's and it acted like it was cold. So I figured I'd run it up and down his driveway a few times to warm it up. Well then it started to sputter and cough a little. So we pulled the carb and everything looked ok, but now as soon as I tap the throttle it splits and sputters. If I kind of feather it I can get it to go wide open but not very good. In my haste I bought a new carb but the issue is still there. Now the only thing different I did between my house and my buddy's is I filled up with some leftover 32:1 mix. Any suggestions. I'm going to check the exhaust to make sure there's no rats nest in it. I'm also thinking maybe the fuel delivery is weak. Oh and before it gets mentioned I have no air box, nor can I find one anyplace. So I had to make a pvc snorkel with a cone filter on the end.
