gas pouring out of secondary boosters?!?!?

Went to start the car this morning after it sitting for a long while. Cranked it to fill the float bowls, and the car started, but idle was terrible and it was smoky. Turned the car off, pulled the air cleaner, and saw (and heard) fuel pouring out of the secondary boosters. The contents of the secondary bowl emptied into the main body. On the plus side, all that gas dumping through the manifold into the cylinders explains why I get a whiff of gas in the oil

The carb started life as a holley 650 dp, but I replaced the main body with the proform. I'm digging through my "Super Tuning and Modifying Holley Carburetors" book, but can anyone shed light on why this is happening? The primaries were not leaking. Would an old/bad gasket cause this?

Thanks,

JLW
