Ok I checked that and didn't seem to have any cracks. A poor air filter couldn't be the cause could it?

Thanks for the reply. I'll take a look again today when I get home. Yesterday I sprayed carb cleaner on the boots yesterday but it never change the idle until I sprayed directly into it.

Hello my name is Josh and I'm new to this forum. I have a problem with my 03 Quadrunner 250 Idling way to high. I have rebuilt the carburetor and gave a proper cleaning. I have tried adjusting the idle screw but nothing happens. From what I can tell I don't have and vacuum leaks. When i spray carburetor cleaner on the air filter side it idles down to normal rpms and then after about a min or 2 it goes right back up. Any help will be appreciated im at my whits end with this. thank you
