So heres the deal i picked up a 2000 xplorer 400 that was not running, long story short i got it running and in all gears. my question is the issue with my idle adjustment screw, no matter if i screw it all the way in or all the way out it does not affect the idle whatsoever the only way i can adjust the idle is through the throttle cable on the handle bars. Am i doing something wrong here? what could be the issue? Air/fuel adjustment?
Thanks

are you sure it's the idle screw and not the air screw?

 

[MikeRost]

the bigger knurled screw is idle correct?

correct.
Take the top off of the carb. and see if you have installed the slide correctly, on some of the older ones the pin that helps you align the slide wears down to much and you won't be able to move up the slide with the idle scvrew.
Also make sure the carb. is all the way in intake boot.
