Thanks, Jon
The Q-Jet was advertised as a rebuilt. I think they are still on ebay. Unfortunately he purchased the carb about a year ago when he was gathering components for the restoration. I'm sure it's to late to do anything about it now except for your suggestion of a door stop. I'm not sure what the number code was, but nothing I have ever seen. He has since moved on as it runs well with a real carb.
As always we appreciate your insight.
