Tecumseh HM80 Will Not Drop down to Idle

I have a Go-Kart with a Tecumseh HM80 Engine. The Motor start fine but the engine revs to high and with not drop down to idle. If I manually move and hold the linkage it will run in idle but as soon as I let go of the linkage it revs back up. Don't know if a spring should be pulling the linkage to idle or what? This is a go-kart so the drive puts power to the wheels when the engine starts. Please Help. I got this go-kart used from somebody with this existing problem.

Sounds like the governor is disconnected, and there is no throttle return spring attatched. You may just want to connect a universal throttle return spring to the throttle.
