Out of time, bad condenser, points out of adjustment, plug wires on wrong, carb not squirting fuel into intake. Just a few suggestions. Take a plug wire off the plug and insert a phillips screwdriver into the wire and hold the metal shaft near a bolt head or other ground and have someone crank it for you. No spark it's electrical. A spark and it's probably a timing issue or fuel issue. I'm sure you will receive more ideas soon. Good luck.
