72 dart 318 starting sequence

Let's go back in time. To when these girls were new. And how you are SUPPOSED to start them

You floorboard the throttle and let it up. ONCE unless it is extremely cold, say, below zero, and even then "depends on the car."

This is a "learned" procedure. Often on these old girls, in "warmer cold" weather, say, around freezing or maybe 40's F you didn't need to floorboard the throttle, but learn to just partially move the thing enough to actuate the choke. This did not pump a particularly large shot of fuel into the carb

Then you crank it. WITH FOOT OFF THE THROTTLE At that point the choke should be set fully closed. When the engine fires, or even tries, the airflow will somewhat pull the choke open against the spring, allowing some air. As the engine fires and speeds up, and generates engine vacuum, the choke pull off pulls the choke open a certain amount which is set by an alignment procedure and gauge (drill size)

Then as the engine starts to warm up, and the choke state relaxes, "kicking" the throttle lightly will release the high idle and bring the thing down to an intermediate idle speed or even "warm curb idle."

BEAR IN MIND that a properly adjusted choke DOES NOT EVEN NEED an accelerator pump shot!!! The extra fuel to start can be provided by the choke itself "Pumping the gas" multiple times should NOT be necessary, except in extreme cold, down into the "20's F or near zero
