Bruce,
Since nobody else has answered your post, I thought I would chime in.
Did you buy the carb from Holley or another distributor, who may have jetted it leaner primary richer secondary?
Some more info would help, is the carb a vacuum secondary?
Does it not have a power valve in the secondary metering block?
Quite normal to have richer jets on the secondary side without a power valve.
