I guess the first thing is to evaluate where you are. Does the motor turn over and, if it does, is there compression? It is does, then check for spark. If not, try pulling the plug and soaking the piston / cylinder with a mix of half ATF and half acetone (or use something like PB Blaster) to see if you can get it to break loose.
Once it turns over, check for spark.
To do that, you will need to mount the coil toward the top of the down tube, connect the coil to the wires coming from the generator, install a spark plug lead, and obtain / install a 6v battery. Use some very fine sand paper to deglaze the points before you test. Make sure the switch located on the left side of the tank is in the 'On' position. Wiring diagram is here:

If you have spark, on to the fuel system. If not, double-check the wiring & the point gap. If no joy, then try replacing the points and condenser.
