Do you have the angle plates under both carbs as well. As you said it sure sounds like it is running out of gas in the secondaries. Looking back in my records with my setup(single WCFB) I ran a .095 in the primary a .059 in the secondary & 75-1161 metering rods.This is at about 3400 feet elevation.
I suggest obtaining a 10-109 Carter strip kit putting in real "rich" secondaries like about .065 & see what it does.
