Stop in for a cup of coffee

So, took the Demon to the car show and swap meet. Ran well down there. When there, Dad noticed my vacuum advance was disconnected. I hooked it back up and it ran like ****. So bad that I stopped and unplugged it, leaving the tiny vacuum port on the carb open. Got home and plugged it back in and adjusted the idle mixture screws some. While doing that, I saw the water pump pulley had a wobble. Shut it off and found the bearing was bad and the fan was about to eat my radiator. Got a new one ordered. Maybe the running issue was so I could see the bigger problem??
