Tools:
Pliers, Screw drivers, Socket set, Wrench set
Parts Used:

The repair was pretty straight forward. One aspect that took a while to figure out is that you have to remove the jet and tube through the main jet adjusting screw on the bottom to be able to remove the upper carburetor assembly.
Also I had to slightly ream the holes in the new assembly to get the float pin to fit.

Runs good now.
