First off don't start messing with anything you haven't changed. Like the timing. I would start with making sure fuel is getting to the cylinders. Start with easiest first. Is their sufficient fuel in the tank? Is gas making it to the carb? After cranking it, are the plugs wet? If so, next check for spark at each cylinder. If one or some are getting spark then you can narrow it down to the cap or plug wires or plugs. If no or weak spark to all the cylinders then start looking at your points, condenser and related wiring. Good luck and let us know what you find.
