I have a 95 artic cat cougar 550 LC that doesnt want to stay driving at high rpm for long. as usaull ill get it running with full choke then after like 15 secs ill turn the choke off then it will idle around 1500 to 1700 rpms but once i give it any sort of throttle it boggs down and will kill itself if u keep trying to rev it. But if u flip the choke on while ur trying to rev it it will rev up like any other machine and run great for a short while , so with that i figured that its not getting gas. So i took the carbs off and took em apart to make sure nothing is getting clogged witch there wasent. The bowls were full of gas. so then i checked the lines but there fine too and the fuel pump is working properly oh also fuel filter is good too. Now that i know that my carb is getting. gas im thinkin it has somthing to do with the idle screw and air screw mabey they are wrongly tuned or somthin. any suggestions would be great
