An air balanced carburetor will help to some extent. Air passing through the air horn of the carb will have no effect on the gas in the bowl of an air balanced carburetor. Any air filter will have some effect on the amount of air that can flow through the air horn of any carburetor. From a performance stand point, an engine is an air pump. The more air that an engine can pump the more power it can produce. Back in the day some would remove the air cleaner from the carburetor to get more power and it worked and the carburetors were all air balanced. When you look into the air horn of a modern carburetor, that little tube sticking up with an angled tip is the balance tube. The balance tube helped but didn't remove all of the air flow restriction caused by an air filter. I run engine pans and don't run mine on dirt roads where dust levels could be a problem. Thats not to say that I would never drive on a dirt road. If its dry and dusty I would use a different vehicle. Mine are just fun cars and are not used for primary transportation. I don't necessarily feel that air balancing the carburetor is a bad idea. I just don't feel that air balancing the model A carburetor or an air filter is necessary unless they will have to be driven in extreme dusty conditions. I feel that under the right conditions the model A will give better performance and gas milage with no restriction of air flow through the air horn of the carburetor.
