Pressure Regulator

Is there any reason I cannot just pick up a regulator and throw it on the line to see if that helps my carb being too rich? I have a rubber line I can plumb in, temporarily, to bring my pressure down. If is see lower readings on the AFR gauge then I will permanently attached it to the fender well and pick up some hard lines.


Or pressure gauge could be attached directly to the carb feed line to find out what the pressure is.
