2003 Suzuki Quadrunner 250 - High Idle


Recommended Posts

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

Check your intake boot for cracks. My buddy just went thru hell trying to fix an issue like that & it ended up being a bad boot. He rebuilt the carb, including choke curcuit, tried a new carb, then was looking @ timing before he found the bad boot! Lots of wasted time and money.
