Slow, Driving Rustoration 1972 Dart

I have the interior back in, waiting on cluster light sockets, they came in but were the wrong size. I'll post interior pictures tomorrow. I finally did a tune-up today after getting the Pertronix Ignition installed. New spark plugs, idle mixture set, vacuum leaks plugged for now. I had been experiencing hesitation on anything more than very easy throttle and it would cough and die. Tried to test the vacuum advance and found out that the diaphragm must be shot. It wouldn't even develop a vacuum there, which was obviously one of my leaks. I set the timing a little advanced and it takes off much better now but still boggy on full throttle take off attempts. I managed to do a little one-legger in my driveway today lol. Here is a video of the engine starting and idling after the tune-up.
