Why does this 42 Year Old BMW NOT start? E24 635 CSI - Restoration Part 1

Welcome to my first ever YouTube Video! This is the first episode of my red E24 Restoration Series. Our first goal is to get the engine running so we can bring this beautiful 635 CSI back on the road! After that we will restore this car as good as we can!
