Also sounds to me like carb balance

When you put the airflow meter over the carb, make sure that you get a good fit. Also recommend that you plug the hose from the intake manifold to the air cleaner before starting. You will probably find one carb "off the chart" and one not registering at all when you start out.

This is not a job for the impatient.
