If the fuel issue is good. Take the line from the Carb. Put it into a can and crank engine over. Stop and see if fuel is in the can. No ignition just hit the starter. Got fuel? Pump is working. No fuel? Crud from the tank got the pump. Replace or rebuild if you can. Got fuel, good. Test for compression. Two out of three. Check for spark. Got spark? 3 for 3. Now, you can start on the tune up. This chart will be helpful:

Get the points set. Set the timing. Start. will it idle? Use a vacuum gauge to set the timing, adjust for max vacuum, then back off about 1 inch mercury. With it at idle, set the idle mix screw to max vacuum. Put on a dwell meter, it will tell you if the points are right. So far so good? Now with it warmed up set the valves. Then with it at idle blip the throttle and watch the dizzy. Did the dizzy move? Yes, good. No? vacuum advance is not working. At this point you can try to rev it up some. Is it smooth? Yes? Done. No? More to look at. Let us know how it works.
