Hi All, I've got a 66 stang with a Holley 1940 Carb on a 200 I6 Engine (Engine is stock as far as I know). I've rebuilt the carb a couple times over the years. After the last rebuild it never ran how I wanted to for a couple years so I finally took it to a carb shop. They tuned it the best they could but said it needs a carb rebuild where it was running like 10x richer than it should be. I was initially going to have them do it, but want to give it one more shot on my own. I'm guessing where...
