Carb removal is pretty straightforward. Remove air cleaner. Mark and remove any vacuum lines. Disconnect choke stove (if applicable). Disconnect throttle linkage. Disconnect fuel line (put a rag under the fuel line so you catch any fuel that drips out). Remove 4 nuts that hold carb to intake.
As far as tools go, I would probably take a set of combination wrenches, a 1/4" or 3/8" socket set, a pair of pliers, some WD-40 and a few rags.
