My wife and I are staying a few days with my grandma in Oklahoma before we go overseas for vacation. My grandfather passed away a few years ago and I've been going through some of his things. I found this carb tucked away in the back of a cabinet in the garage. It's a Carter and it still has the brass tag. Best I can tell it says 078S on the first line and has a larger B7 just below it. What would this have fit originally? I'm using my phone to post this and I'm not sure if I can post pics from it but I'll give it a try.
