start with the points, i had a cb360 with stuck points and no sparky. if they are clean and open/close freely when the motor spins check for power going to the coil(s)

There should be a condenser (also called a capacitor) in the circuit. Check that. If your local shop doesn't have the equipment to do so you may have to just buy a new one and install it. Check wiring to the coil, and from the coil to the spark plug. If all wires are okay, check the coil primary and secondary windings. Most manuals will give impedence for both.
