Dollar, That Wico X Mag has a bearing where the older C Mag has a bushing so they do a lil better in that regard. If theres excess shaft wobble running a lil wider points gap may provide temporary band aid relief. That loss of complete spark sounds like they may be some high voltage breakdown or arcing happening possibly from a cap or rotor problem. Id inspect the cap with a fine tooth comb to look for tiny cracks or carbon traces or unusual inner cap terminal or rotor tip problems like oil or moisture (use a hair dryer to heat up n dry her allll out) or carbon build up or shiny brass from rubbing. Make sure BOTH the caps lil springys, where it mates with the coil and the rotor are lining up n mating ok.
If it has the external push to kill button/switch make sure it nor its wiring isnt getting shorted.

If its NOT a cap or rotor problem and happens once all is warmed up, the coil could be breaking down internally or the condensor may be at fault. For no more than they cost Id replace the condensor and the points if they are burned or pitted or carboned up. Also insure the condensor is screwed down tight for a good ground and its wire to the points where the coil wire attaches are alllllll good n clean n tight.

If youre absolutely sure the points n condensor and cap n rotor are NOT at fault (try easy cheaper things first) and the cap is okay but she still seesm to totally shut down ignition wise, then Id suspect the coil is breaking down.

PS you might check the plug wires and use copper core if they need replaced.....

Let us know
