If you are sure you have fire and gas to cylinders and have timing approximately correct loosen vacuum advance clamp. Have someone crank while you sloooooooooowly advance and retard distributor you should be able to hit optimum start spot fairly quickly. I found loosening the vacuum advance clamp allows you to more gently move distributor without fighting vacuum line
