I agree with the above advice. You need to go back to the the basics. If you have fuel, compression, and spark it will run if you get them to come at the right time. Don't take anything for granted. Check the compression on all cylinders. Test the battery voltage, test the coil, condenser and points. Set the points and adjust the timing so the points just open when #1 is at TDC on the compression stroke. Make sure the wire to #1 plug goes the the terminal on the cap that the rotor is pointing to. Make sure wires run clockwise from #1 to #6 in the firing order. Start from the fuel tank and be sure the line is not blocked. Check the filter for flow. Test the pump. Make sure accelerator pump is squirting and fuel in spraying into the manifold. Check to see of rockers are opening the valves If those things happen and the muffler isn't blocked it will run if not fix them.
