I have a 78 Malibu with a 305 all original. It has the stock Rochester 2 barrel carb. Every morning I try to start it. I have to put gas or starting fluid in the carb to get it started. After it starts the car is fine. When I go somewhere, turn off the car and turn it back on it’s fine. It’s only when it’ss cold start. It also bogs down when I step on the gas. The carb was rebuilt also. I’ve put 91 fuel and Berryman fuel injector cleaner as well. Any suggestions or tips?
