I was told close to 60 years ago to turn the adjusting screws out a couple three or so turns to start with and not to worry about the amount of turns because after the carburetors have been apart most will be different than when new but will still adjust for proper running.

Adjust the screw until the engine will run the fastest RPM's and then turn it back in until you notice a slight slowing of the RPM's. I was told that it would be as close you could get without having the engine under load. It worked back then and has all these years. I have never had to ask how to get a tractor carburetor adjusted to run properly since. I have never hired anyone to work on any of my tractors.
