Identity of Carb thread FZ22 - Derek Sheldon - 30-06-2020     Please advise thread as indicated in picture. Not for this carb , just at hand. Thanks RE: Identity of Carb thread FZ22 - David.H - 30-06-2020 Probably Metric? RE: Identity of Carb thread FZ22 - Ian McGowan - 30-06-2020 As David suggests, I believe that all threads on Zenith carbs of the period were metric. RE: Identity of Carb thread FZ22 - Derek Sheldon - 01-07-2020     Having tried metric threads, 4mm appears to be the one. The thread seems to be very worn and wouldn’t take much to totally strip it. Have taken the step to pen it out to 3/16” BSW which appears to be a good job. Once again thanks for the help
