Hello I have a 2002 sportsman 500 HO and can’t seem to figure out what is wrong with my atv. I bought it used and was trail riding one day no problems then took a break turned the fule to off and forgot to turn it on ran the atv and it started bogging out. I switched the fuel to on immediately the atv did not die but now when I give it throttle it feels like it’s going to die and slowly creeps up to speed but is allot less power than before. If pull the choke while driving I get full power and pick up but as soon as I press the choke back in same issue. I have had some backfiring but not sure if this I caused by me pulling the choke. I have replaced the spark plug, inline fuel filer, 3 way fuel shut off valve, cleaned out the carb which was not that dirty. I can think of what I am missing or have overlooked. If anyone has help resolving this issue that would be greatly appreciated.
