Toro 22" Mower Throttle Cable Adjustment

I have a 22" toro recycler walk behind mower. I was mowing the lawn this weekend and when I was done it wouldn't shut off. I saw the extra slack in the "throttle" cable (not sure if that's what it's called or not but it's the long cable that runs down the side from the handle that you hold down to start all the way to the throttle on the engine. Once I adjusted the cable manually I noticed that the handle had so much slack in it from the cable. It seems like the cable has about 2-3 inches of slack now thus not allowing it to start without me adjusting the cable. I can get thru about one run on the lawn before it just shuts down on me again cuz of the slack. Is there a way to adjust the cable permanently or do I have to order a new "throttle cable assembly"??? The lawn mower is only 3 years old and just out of warranty. Any ideas would greatly appreciated. If there's more info that you require, please ask I'll try to get it.

 

The engine brake cable on most of the Toro mowers are not adjustable, if it has too much slack you most likely need to replace it. They are not overly expensive usually around $10.00 or so.

In a pinch I have tied a knot in the end of a cable to get by until I could purchase a new cable.

 

Ok that's kind of what I was thinking. I know on some of them that you can but I never done this before. I looked up the part from Toro and it was like 16 bucks so that's not really bad at all. Thanks for you help!
