I have a 2004 polaris sportsman 500 ho and i just replaced the needle and seat and it is still getting flooded out with gas. i adjusted the float and the bowl isent overflowing with gas. im stumped. i have checked the diaphram on the top of the carb and that is fine. it will idle for a while and then start to die a little and if you give it gas it just boggs out and dies and its a pita to get it started again. any ideas would be great.
