Default Re: flow testing Model A Zenith carb jets

Here are some charts to make life easy.

I tested many jets using the Ford column length.

I did a lot of error checking and repeating and found the results were very consistant.

Most seemed to flow too much by a little to a lot and some were on the money. A few did not have a nice stream indicating there was a problem with the hole and flow.
