HELP! Throttle stuck! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a 71 C20 with a 350 and Quadrajet carb.

I've never driven it at wide open throttle, but today I let my friend drive the truck and he drove it around the block hard, and floored it a few times. Then, the throttle got stuck and now it idles at 3000 RPM!

The linkage seems to be fine- it's returning all the way and is responsive to the pedal. So where should I look now? What could be the problem? I'm thinking it's stuck somewhere because the truck doesn't get driven hard often and maybe today after the throttle opened up all the way something got stuck.

Any help or suggestions?
