Maybe you are off your meds (or need something to calm yourself) no need to explode, your nomenclature of parts needs improvement is what I meant.
The black component is a ignition exciter coil, the little dude below it to the right with the white wire and two blacks under the small nut it the condenser. Perhaps a manual for parts or the service manual will assist in properly describing the issue would help.
If after removing the exciter coil to change the plug wire, and reinstalling it makes the flywheel contact the core of the coil, then the coil is just out of alignment. Loosen it and press the coil towards the crankshaft and then try to fit the flywheel back on. The clearance between the two is tight, so you might need to play a little.
If after it kinda sorta fits but scrapes, use a sharpie on the ends of the iron core and paint the ends, return the flywheel and rotate it a couple of turns, you will see which end is rubbing, only just loosen the screws and sightly tap on the end that touches and retighten.
It will take a little patience.
