Holley 1050 issues

[bearcat]

I have an old and recently rebuilt holley. When I turn the electric fuel pump on, fuel pours out of the valves next to the main fuel bleeds through that vertical tube. The car also runs very rich, I cut back the pressure to 5psi for now. It died at idle a few times today and very difficult to get started. I never had this problem before, but was in much cooler location. Used to run great. Now runs rough at low RPM and is awesome when wide open.

Is the fuel spitting out normal with electric fuel pump?

How do I lean this thing out? Is it only the idle mixture adjustments?

Thanks for the help.
