In my case, the hot air tube is not connected. That is the reason I’m converting to an electric choke. I am plugging both ends of the heat tube in the intake and going with the electric choke.

I bought an electric choke from Mike’s Carburetors, and he advised plugging of the nipple going to the choke where the hot air tube normally connects. I will also plug the grommet on the front of the carb where the inlet tube goes.
