Thanks MacLorry! That is EXACTLY what I was looking for!
What was probably throwing me off is the fact that one of the "hands" of the spring is sticking out from the top of the lever by about 1/8 inch, which does not really look right, but according to your picture, that's just how it is.
Also, I found a way to prevent the cables from freezing. While trying to free up the cable, I actually boke the chute deflector control cable... Oops! The machine sleeps outside, in an non-heated shed, so frost is always an issue.
Instead of buying a new cable from Ariens directly, I bought a $2 bicycle brake cable from a local bicycle repair shop. That cable is of MUCH better quality than the one used by Ariens. I greased the cable with water repellent gear grease (again from the bicycle repair shop) and inserted it in the original sleeve. (The one from Ariens). Also, I sprayed the inside of the sleeve with a silicone based lubricant before inserting the replacement cable in the sleeve.
That kind of cable normally has 2 types of "hook", one at each end, so you need to cut the one you don't need. For the chute deflector control, there is one of the ends of the cable that matches exactly what you need for the end of the cable that goes on the chute deflector itself. The other end on the original Ariens cable is actually a ring, so I just tied a knot in the steel cable, and locked it in place by "sandwiching" the cable between 2 washers held together by a nut and bolt. Not pretty, but functional!
Of course, I DO NOT recommend that you start cutting away your original Ariens cable to replace it! It's just that if you accidentally break yours, you can make a repair that will cost you less than $5, and will actually work better than the original part! The thing is that the replacement cable I used is made with better quality steel, and the threads that make up the cable are more tightly woven together, which makes the cable slide better inside the sleeve. Also, the grease prevents water from getting into the sleeve, and the silicone lubricant will keep everything slick in case ice crystals do form inside the cable sleeve.
Oh, and that little rubber thingy that covers the cable on the end of the cable that is connected to the deflector? I filled it with grease also!
Again, thanks for your help, and I hope this little piece of information can help others in return!
