36" Craftsman Model 536.887000 Throttle Control or Governor or Both Problems

The carb on my old craftsman snowblower was flooding. I know basics of how all the parts of the carb work, but when i got it apart it was clear I didn't know enough. I got a local small engine guy to help me get it all back together, but in the process of reinstalling it I managed to put too much pressure on the linkage that goes from the governor to the throttle control and broke the spring in the the control unit. This same small engine guy helped me get the control back together, but it was pretty tweaked and didn't want to work so I ordered a replacement part. This part doesn't work either and I am coming to realize I just don't understand how it is supposed to work. The control is a lever that you slide up and down that somehow makes a smaller lever with a spring wrapped around it move. This smaller lever has a linkage that goes to the governor lever. There is another smaller linkage that runs back from the governor lever to the throttle plate on the carb. When I slide the throttle lever the smaller lever on the control unit doesn't move. It will push forward and increase the throttle, but when i pull it back it wont reduce the throttle. When I took everything apart I took the governor lever off to disconnect the linkages. I have come to realize that the position of that lever is important so it is clearly out of adjustment also. Can somebody explain to me how this system is supposed to work? It has been completely disassembled so anything that needs to be set a particular way is going to be wrong. I need to someone to walk me through getting it back together. I have been farting around with it for days, and now I am sitting through a blizzard and it still wont work. ugh.
I am going to try to attach a diagram I found that shows the assembly that I appear to have.

Rotate the governor shaft as far as it will go in the direction that would give full throttle. Set the carb to full throttle as well, and install the governor arm in this position, while holding both at full throttle. This will reset the governor.
