This is my Magnum cold start every time.
Electric fuel pump, return fuel system with an Edelbrock 600 electric choke and HEI ignition.
I turn the key on and give it a couple of seconds to make sure the carb is full, twice to the floor with the throttle and BAM.
The high idle is set so it really only chokes and holds the idle up in the winter, so during the summer I feather it just a little and then it idles on it's own.
