I have a 2004 600 Sportsman. I was wanting to know what the factory setting on the idle screw and fuel mixture screw should be. I don't have a manual yet. The thing runs rich and has a hard time starting, like it's been flooded. I was wanting to lean it out just a bit., but need some where to start. After it warms up it runs great. I haven't had time to mess with it because I've been working on my YZ 400 F. Thanks.

 

Do a search on this subject , there was a service bulletin on this, especially on 600's, it's about taking the brass plug out of the bottom of the carb,over the air screw and adjusting the air screw further out.I think it said to go like 2and 1/2turns and then fine tune.
