I don't know what I did but I had it out on the highway today and its like it was when I bought it! Obviously something in my rebuilding of the carb or the parts I used was affecting it. Most of the problems are gone. My guages have been staying off since before I installed it so I can't track MPGs yet. I think it might be worth it to go ahead and do the timing and balancer belts when I install the distributor. Tomorrow I finally get it in for the front end alignment since I did all the joints and steering parts last fall.
