    The newer carbs have an electric auto choke. All it needs is one 12 volt wire...

    sounds like he is talking about the hot air choke. The one that goes into the exhaust crossover.

    Go to the junkyard and find a junk quad with electric choke, grab all the choke parts off of it and swap in an electric choke.

    be aware, you can't do that swap easily on all Q-jets. It canbe done, but its not a simple unbolt/bolt up affair. (dad converted his to electric choke, took some effort, I was surprised actually at how much different his particular carb was from an electric choke one)

    My quad off my my vette was hot air choke..... converted right over. It worked right after a bit of tuning.
