Sounds like you need to prime the carburetor before starting the car. You should always prime the fuel bowls before cranking or starting the motor. Reason is todays gas evaporates and causes the fuel to gum up and stick the inlet valve. Allowing the motor to draw the fuel to the carburetor after priming will prevent blowing the power valve in the carb as well. This is somewhat old school with carburetor cars. If you store your car for a length of time normally you should put fuel stabalizer in the system but always prime the carburetor if you take it out of storage to allow the fuel system to draw fuel from the tank. As a precaution don't crank the motor while pumping the gas waiting for the fuel pump to draw the fuel to the carburetor as this is called dry pumping and will blow the power valve in the carburetor. The motor won't idle or accelerate properly if the power valve is blown.
