Does anyone know what the tube running from the carburator to the exhust is called and where can I get one
It's called a " Thermal Choke Tube " and here's a link to it: http://www.autokrafters.com/v4/go.g...=&modelId=&yearId=&&ACESSearch=&product=25811
This is pictures from a 170. Not sure, but I believe it is the same or real similar. Hope this helps.
