Tecumseh Throttle HMSK105

Replaced throttle spring & governor link. Throttle up ok but arm on throttle doesn't return when throttle down. Any suggestions?

Welcome to the forum! Does everything move easily and freely when the engine is off? No binding or sticking in the linkages? Are you talking about the actual throttle plate itself (the one that the governor itself controls), or the portion that the user controls, which sets the "input" (if you will) for the governor?

Running or not running? Not running, the gov has no source of energy to pull closed . . . . If running, gov may be broken, or the arm attached wrong. The spring pulls open, the gov pulls closed, and the point where they balance defines the governed speed.
