To tell whether a carburetor is made out of pot metal or aluminum, measure the two carburetors together and record their total weight. If one of them is heavier than the other, then it is pot metal. Aluminum is a very light but strong metal. For this method to work, the two carburetors must be of the same size and measurement.
