318 Running Richer w/ Carb Swap

Has the fuel pump been replaced lately? You might want to check the pressure. 3 or 4 pounds is all you need. It sounds like it was running rich before the carb swap so it is probably something else.

I have not replaced it myself and it looks like it's been on there long enough to say previous owner had not either. Would a stock mechanical pump really put out more pressure than needed? I have one on the shelf that I could swap if need be, but I'll fuel pressure check to the troubleshooting list.
