I just received 2 new Carter YF 2100S carbs and noticed three ports on the bottom of the carb. The Rochesters only have 1. Do I need a different insulator and gasket for these carbs, or will the Rochester insulator and gasket work? I guess what I am asking is can I ignore the two additional ports on the bottom of the YF?


How did all this sawdust get under the hood?
