I dug through my old parts and found a NOS rotor - but it's a 29707-63R. The Hummers didn't use 297xx parts, so I think this fits a Sprint. No help.|
I would suspect the coil before the rotor. The coils in these mags were known to be the weak link.
If I remember correctly, these magnetos were produced by Bendix-Scintilla, who made aircraft magnetos, but also sold flywheel mags for small equipment (snowblowers, rototillers, etc) during the 1950s and 1960s.
I've contacted a company who re-magnetized my XLCH rotors. They're not familiar with Hummers, so they're going to do a little research and call me back.

62 Scatt getting closer but still a few issues.
Magneto does not appear to have sufficient magnetic force to create the required 6 volts. Checked the ignition coil and it passed but it could still be bad. Bike runs with a 6 volt battery bypassing the magneto entirely.
Not having any luck so far finding a place to re-energize the magnet but I know it is done. After that if there is still an issue it could only be the ignition coil. I already replaced the spark coil, plug, plug wire and points.
Any ideas where to send the magneto for testing and repair. I live in Minnesota but don't mind shipping it somewhere.
