My experience has been that three important things are essential for a good functioning Zenith. The internal passages must be open. The float level should be properly set, and the jets should be flow tested and re-sized.

Original jets can be incorrect as well as reproduction jets. Over the years people have been pushing welding tip cleaners through them. I flow test both originals and reproductions, solder them closed and re-size them. Either one will work fine as long as it is the proper size

Flow testing and re-sizing is a tedious and time consuming task. A Model A club should build a flow tester and have a flow testing seminar every so often. Our club has one scheduled for next month.
