Maybe the first thing Big Poppy warned me about when I got my TBA was to never twist the throttle before starting. Being a dutiful friend, I never questioned his advice and never twisted the throttle but did choke it and did turn on the ignition for a few minutes to let the pre-heaters work, as he also suggested.
Your graphic description of what can happen only makes that Big Poppy even larger than life...and a millionaire,too.
