i hav a bronco witha 351 m and i was driving it and it started spitting and sputtering and i couldnt figure out why. well i put a new carb on it and noticed vacuum lines were layin everywhere. could this be why it was dying? the pcv valve has two ports on it and one goes to the back of the carb and there was no line for the other. i stuck my thumb over the hole and it idled great! is does anyone know how these vacuum lines go on?
