The body looks to be the exact same size so if you want to buy the knockoff and swap parts, you may be able to keep the autochoke. It's still cheaper than a rebuild kit. Personally, I would just rip off the linkages and stick with a tried and true primer. The throttle cable looks to be the common design I've always seen.
Just removing that carb looks like a total PITA. I know on mine, getting to the governor spring ticked me off because I had to remove the entire top cover to be able to reach it.
