A little more than that Jordan, pay attention in your physics classes and you will understand it better. The material is a thermal insulator and as Ken explained, it is a poor conductor of heat and insulates the carb from thermal transfer from the mainifold.

In other words I wanted to make sure that he wasn't just overlooking it and hadn't seen it before.
