Purchase a complete set of flow-tested jets from Mr. Renner and install them in your carburetor. He will tell you exactly what flow rate each jet tested at. The jets all work as a set for good power and good fuel economy.
Or you can build the flow test apparatus. A lot of work for one set of jets. Worth the time if you think you may test a larger number of jets (for yourself or others).
You also need a good sealing float needle valve on the carb to get good fuel economy, and all of the jets and the drain plug on the carb must seal tightly.
You need to have a "dry carb" on the outside, no drips, weeping, etc., when the car sits.
