Was definitely the carb. Put the Holley on and now getting 20 Vac at idle. Took a short drive around the col de sac and no stumbling. Now I have to get a different kick down linkage and throttle cable.
you should be able to use your original cable and kd linkage with an adapter from holley. I have one that I am not using that you can have if you want to pay shipping. Shouldn't be more than a buck or two. Pm me if you want it.
