Just for info: Many here & in YBM have indicated they have given up on their early Holley "Teapot" carbs. In some case in such frustration they have likely scrapped them. I have here a sheet from Pony Carburetors inc. While not dated it appears to be reasonably recent. They apparently rebuild the early Holley's & even if people don't want to go that route, their core charges range from $150 to $225. So don't scrap ones you are not using, they aren't worthless...
