250C, vacuum problem?

Hi member with my first post. Enjoy the site and have already learned a lot. Purchased a 1971 250C with the Zenith carbs. Put in new plugs, points, wires, rotor ad distributor cap. Changed all fluids, put in fresh gas and started it up. Good compression and oil pressure. Runs well at idle, however when the brake pedal is pushed the idle speed drops and appears to labor. When shifted into reverse or drive the engine dies. I've ordered a couple rebuild kits for the carbs, however I'm wondering if there is some type of vacuum problem as there is a slight pulsing when the brake is applied. Thanks for your thoughts.
