To find out how your carb is jetted is a very simple. It can be done by yourself if you are up to it. Any tune up shop should be able also.
Put a portable air/fuel analyzer probe in the tail pipe. Go drive the car under ALL of the varying conditions and record the readings for all the situations. This will tell you how to re-jet the carb.
While tailpipe analyzers are not the most accurate, they will do for average street driving.

For long engine life, some type of air cleaner should be run.
