I'm guessing you have fixed this or given up after 13.5 years, but here is my suggestion for the next person who has this trouble. If you ran it out of fuel and left it over the winter, it could have a drop of fuel that hardened and plugged one of the fuel ports in the carburetor. I have had this happen and needed to remove the fuel bowl and poke the dried film with a pin. Put it back together and it started right up.
Do not know what brand that is, but you can find choke cables at lowes, amazon .com. or any number of small engine repair shops depending on where you live. An after market cable could be easier to find and work just as well.
Question edited for a lot more clarity, add maker, fix typos, change into what I think you were saying. Manuel is the name of a Spanish gentleman, 'manual' is the word you need.
Manuals in the link, plus the maker. This link show 'M Series' belt.
