Model number? Single coil with two spark plug wires from it? Is the ignition fuse blown? Single fuse, 20 amp, near the starter solenoid and battery? No lights mad no clutch, would seem there is no power to the keyswitch, And voltage has to come through the fuse.

What is battery voltage? What is application? 5 fuses? The engine coils and the flywheel magnet is all that makes the spark. So you have kill wire being grounded by the key switch. The engine starter works, so the keyswitch has voltage. Lights may only come on when engine is running, but clutch should click, if you turn on the key and turn on the clutch. ??? Do you have a voltmeter or test light to follow the voltage trail?

yes I have a voltmeter , I will try and trace through the wireing into & out of the ignition switch, the engine has two engine coils.

Yes, two coils, if you locate the kill wire that goes to both coils and unplug it, the coils should spark. But it still needs to open the fuel solenoid at the carburetor for it to run. When you checked fuses, did you check for voltage past the fuses and fuse holders.
