Edelbrock accelerater pump

After going over the manual, primarily the secondary side of things since it's mechanical secondaries, could it possibly be I have yet to create enough air flow through the secondaries to draw fuel? Since the car has only been sitting, revving in park, and not having a load on it. I've got pump squirt now and using the plain step up spring since it has 20 or so inches of vacuum at idle in park and doesn't really drop in gear.
