Thanks for the photo Denny!! That's exactly what I was looking for. Now I know that I'm missing the little brass clamp on the throttle control wire. Someone before me bent the crap out of the cable wire trying to Rub Goldberg the connection and finally disconnected the throttle cable.
Thanks again Tim and Jon for your input helping me define the historically correct carb as a Carter W1-574S, and you know what, I found on Ebay a completely restored 574S from a guy out in CA. So, I bought it!! It's been a good day!! Now all I need is one of those glass gasoline filters to enhance the original appearance.
