Hello everyone,
I have a 2002 sportsman 500 that is burning super rich and blowing black smoke when I give it gas. It smokes quite a bit at idle too, I've been chasing this problem for months now... This isn't my first rodeo and I've tried just about everything I can think of.
I pulled the carb and put a rebuilt kit in it, cleaned it, checked all seals, float, fuel/air mixture screw and jets. I have the fuel/air mixture screw 1.5 turns out. The ATV keeps fowling plugs but runs good at high rpm and higher speeds but sputters a lot of low speeds. It idles fine but smokes. and as soon as you give it gas when in gear it sputters. The choke functions properly and the float and needle all are adjusted correctly.
It has a new air filter, new fuel, and a carb rebuild kit in it. I have pulled the carb at least 6-7 times... Any help would be greatly appreciated. Hoping its not an exhaust lobe on the CAM....
