Husqvarna 700F push mower wouldn't shut off

[Deby55]

I have a Husqvarna 700F selff propelled mower that when I let go of the throtle bar (I think this is what it is called) will not shut the mower off. I noticed there is a cable attached to it and upon following it found that where it attaches to the engine the throtle will get stuck and not move when the bar is let go of. The cable does not appear to go back into the casing. I am guessing the issue is with either the part that is attached to the mower engine or the cable itself. I can not find a description of either of these parts, or number in order to know how to replace it. The cable itself seems it would be fairly easy to replace as it attaches with a pin into the handle and one into the part on the engine. Or if the issue is with the part attached to the engine or could it be as simple as needing cleaned?
