Ed,
If it's a Tilly carb...try 1 1/4 turns out on HIGH. 1 1/2 turns out on LOW to start with. Make sure though you don't have an air leak that's causing high idle, though. There will be one screw for the idle that pushes the same part of the carb that accelerates the engine. Don't have a 49sp or I'd take a pic of it.
Post a pic of the carb if ya want. If the carb won't adjust and you can't get the idle correct, expect an air leak.
