Well I took a the vacuum lines off and tested each carb - rear carb works like a champ front carb hisses....diaphragm is toast and it is my fault as I over tightened the cover when I was swapped the springs out....and of course no one in MD has a 135-6 diaphragm. I have one place left to try...thanks for the help. I am also going to spring is lt silver and not yellow btw...
