Do I need to install the choke for the TT 91? does it make a difference?

I live in Tucson AZ if that makes a difference. I know chokes on cars are usaually for when it's cold.

thanks

Unless you have a fuel pump you will need the choke. The TT choke doubles as a venturi and velocity stack. The bore is smaller than the carb bore and will help it draw fuel.
