Does anyone know how to fine tune a Carb. on a 1978 Indian Moped. The carb. is a Tillotson. I have it running and there is the nedle screw adjustment and an idle screw below that one. I know the setting for the top is usually 1 1/2 turns out. Do I really need to mess with the one below that one?
Also does anyone know where I can pick up a 17 or 19 mm carb to replace the tillotson.
