And just one more thing. I have read that the Rochester B needle valve can hold back up to 10 PSI fuel pressure. I have read that the Weber 32/36 needle valve can hold back up to 8 PSI. My 5.5 PSI is well below 8. So, I decided there was no reason to think I was flooding the carb with my mechanical fuel pump, and my AFR readings after re-jetting back that up. Also, the way the fuel pump is designed, once a pressure of 5.5 PSI is reached on the output side of the pump, it will not keep pumping more gas out. The needle valve must let gas through before the pump can push more gas into the line. So, the fuel pressure will never be higher than 5.5 PSI, which is exactly what the fuel pressure gauge shows. The mechanical fuel pump was never the issue for my initial rich condition. Reducing the size of the idle and main jets, and increasing the size of the air jets solved my Weber 32/36 issues for my engine at my altitude.
