My tiddler quit running! No spark! I tried a known good coil off my dad's TC120 which hasn't been run in a decade, but I tested it for spark before I pulled it. Looks like the HT lead on the TC90 coil was damaged, but it's been working this long.
I have not tested the ignition switch yet, simplest things first, I know...
Other than that, I don't know how to troubleshoot these old ignition systems. Any tips?
