I have run 9.90 with my set up. My carb was built by Jim Boburka.

Have not checked flow from my pump, but I'm going to check that today too. Mine is a Holley Blue pump but it's ancient. -6AN line from regulator to carb through an inline filter.

All that should work if it’s mechanically in good working order. Check the flow before and after the filter. If the flow is low with the filter you might need to take it off. I do not run a filter and never have. I am real careful to keep my fuel system clean.
