Holley 450cfm leaking feul in secondaries
 

Hey i'm almost ready to fire my car for the first time. I have two holley 450's on a tunnel ram setup. The carbs are single pumpers with no choke and mechanical secondaries. I got the carbs and the tunnel ram off my freind and they had been sitting for a long time so i rebuitl both of the carbs, but the secondaries on the one is leaking fuel, its coming from like the sides of the bores right above the throtle blades. I don' even have the secondary throttle blades hooked up(would be too much CFM for my setup) So i was wondering if there is an easy way to fix the leak or just block the fuel passage to the secondaries, please help.
