Carburetor Replacement 2 Cycle Husqvarna 122HD45 Hedge Trimmer (or any 2 cycle engine)

Here I’ll show you how to replace the carburetor on your 2 cycle engine. In particular Husqvarna 122HD45, but is applicable to about any 2 cycle engine.
I've had this old hedge trimmer since 2014, and it stopped working a few weeks back. When I went to Home Depot, I found out it would cost $500 to get a brand new one. Instead, I ordered a new carburetor from Amazon for less than $20.
Here is the exact carburetor I used, right out of the box:
