HELP! 66 cuda idles fine, but not when in gear

I was just looking over your pictures, and I found another thing you can try. Right now you have the vacuum advance hooked up to the ported outlet on the carburetor, pull that off and hook it up to the vacuum Port near the base plate underneath the front fuel bowl. Plug the one you currently have the hose coming out of. Bet you a box of donuts that helps.
