I just purchased a 1957 T-bird 312 CID engine and factory 4 barrel carb. I have not had tme to work on this but the engine does not want to start unless I push down on the gas peddle. It seems the large butterfly on the top of the carb stays closed all the way. So it seems when I can introduce some air with the throttle it will start. I assume this large butterfly valve is the choke. Is there any adjustment that can be made manuly on this?
