I don't think you understand how fuel injection works. Adding more fuel does not increase power. Unless you have a fuel computer you will actually lose power from overly-rich mixutes, plus your fuel consumption will suffer badly.

Replace the secondaries. Don't do it until you have the S-AFC in and wired. Make sure you get it dyno-tuned.
