Sorry for the delay in responding BettyBenz, I don't come through here much. Never really watched the blogs myself. Apparently admin decided there just wasn't enough traffic to justify.
a whiile back you posted a photo of a Solex 4A1. I have one ona 73 280C. On your photo there is what I assume is a choke. It has is a diaphram with a spring in the back and a vacum hose in the front. Is that a choke and were does the vaccum line tie in?
