/6 Holley 1920 economizer lever

@Thomas Shirley there are a lot of more qualified people here on FABO that may have better information but before I started a rebuild on my Holley 1945 I tracked down a "parts only" carb on eBay that was inexpensive just for the reason you described... me accidentally breaking something! So that may be something to look into... but like I said, I'm sure someone else will have a better lead.
