Good News, I was able to fix the gas leak!
I adjusted the carb some but I can't seem to get it to run as smooth as the old carb. It still wants to die with the choke open and warm engine. So right now it seems like it's acting worse than the old carb. I'll try the mix screws some more to see if closing them or opening them makes much difference.
I also noticed that I can hear some tapping from the valves and the oil is not low. My vacuum intermittently fluctuates between 15-16 so I think I may have a valve problem that is causing the low pressure.
