Question for ya'll...I have a 78K5, and the guy I bought it from replaced the Q-jet with an Edelbrock carb. My question is this: The Edelbrock is a 600cfm, electric choke carb. How am I supposed to make the choke work if my 78 didn't come with any electronics? Or does the carb have something like a temp or timing control? Any info would be helpful. Thanks guys!
