Small Engines (Lawn Mowers, etc.): tecumseh carburetors, hex head screws, toro 521 snow blower

Question
I have a toro 521 snow blower with a tecumseh engine. I need to rebuild the carburetor. Where can I get directions for thie procedure?

Answer
happens to be i have one of these in my shop.
as we speak.   the plastic type.  (small)  you need to remove the plastic cover first.  removing the gas cap, and the screws down the sides.  make note of their location.  loosen the bar across the handles which hold lower plastic cover.  you will need to pry that part down some to gain axcess to carb.  there will be 2 hex head screws holding carb in place.  remove them  with a ball end allen wrench.
remove linkage,  and make note of all . remove carb.  clean and service as needed,  and replace.
