leshby, there is a fair amount of service information in the 168-F1/2 owner manual, which you can access through the link I supplied in an earlier post in this thread. Also, while I don't know of a free source for a GS65 service manual, you can probably get most of what you want from the GX200 short-form service manual available free here:

I hope between the 168-F1/2 owner manual and the GX200 service manual you can find what you need, but if not, you might find it in one of the GS65 service manuals for sale on ebay.

We can go through a carburetor tune-up process in this thread if you like. I don't have the carburetor in front of me, so we'd just be working from pictures you'd post plus the manuals. Meanwhile, you did turn the fuel tap ("gas valve") fully on, didn't you? (Push it fully to the right, as shown in the sticker near the tap):

A fuel tap that was turned off but leaked, or one that was internally mangled and just didn't work, might explain your problems. You could test the fuel tap by removing the drain plug low down on the front of the float bowl and checking the flow rate of fuel after allowing time for the float bowl to empty. The fuel should flow full stream with the fuel tap on, and stop with the fuel tap off.
