YESSSSSSSSSS Ive had that before, manyyyyyyyyyyyy times when a plug was fouling.
FWIW I AGREE. If a plug wont fire but will if you remove the wire just off the plug and let the spark jump, its indicative of a fouling plug. The reason for that is if oil or soot or carbon are providing a shorting conductive path for the coils energy, it will bleed off and not rise to a sudden high enough voltage to arc jump the plug gap.
The same (only) set of points and condensor and coil fires BOTH plugs, so if you have a situation where one wont fire but the other one will, typical causes are in the cap and rotor or a bad plug wire or as above, a bad plug. You can swap plugs and wires to see if its a wire or plug problem or if it stays on one cap terminal alllllllllll the time regardless.
Clean and check and gap the points (replace if badly burned or pitted) and install a fresh set of plugs and see what happens, if no cure post back

On our first cosmetic restoration, not having a manual, we carefully marked the wires, taped the magneto in the position it came off, and were careful not to turn the engine over while we had these components off. We thought we could get by with this since the engine ran perfectly and would not need any internal work. After the cleanup and painting was done, we began reassembly and finally came to t
