72 dart 318 starting sequence

Thanks so much what an explanation! so if the choke doesn’t open with the pedal pushed down what might be wrong I’ll post a pic in a couple minutes when I leave for work. Thanks again
Probably just an adjustment. The choke unloader is different in all carbs. If you look at the choke linkage at full throttle you will see a tang that engages the chole linkage and cracks open the butterfly. You may catch a diagram if you Google it.
