So I’m the new proud owner of a nice 1976 Corvette. It doesn’t need a little bit of work, but it’s not any work that I’m afraid to put into it. The only thing is I’m new to working on classic cars and carbureted engines. And before anyone makes fun of me, I’m only 18 years old, so that’s my excuse for not having that kind of experience. Anyway, for some reason when I start the car and let it idle and get warm as soon as I press the brakes to shift into gear, the engine stops, and I’ve tried to look up what that might be whether that’s a vacuum issue or anything of that nature and I cannot figure it out to save my life. If anyone could give me some guidance, that’d be pretty awesome. Thank you
