Something is wrong if you're having to prime the carb everytime you start your car. The carb should have gas in the fuel bowl without needing the pump to fill it each time. I can let my car sit for a month or more, and it fires right up with no choke, my setup is just a Carter street pump feeding a Holley double pumper. The question you should be asking is why is my carburetor empty and where is the fuel thats supposed to be in it going?

My 2-cents says you've got other problems. I wouldn't be suprised if you're dealing with a flooding issue, not lack of fuel (??).
