Adjusting the timing on a 34 ford v8

[Rsb43]

Any suggestions on where to start with adjusting the timing on my 34 ford v8? I am assuming the lack of power and popping through the carb has a lot to do with it........all the way out and work in? Or run the adjusting bolt all the way in? Is there an old reference guide on how to properly adjust timing? Everything has been rebuilt......
