I got the C together today using parts from the other C, which is now almost all dismantled. I swapped the entire steering assembly and the front end, the radiator and thermostat housing, the sheet metal and the starter. I still need to put the bolts in the front of the hood and get a shorter fan belt and some threaded rod and put on the alternator and wiring. When I started it up and drove it out of the shed everything seemed fine except that there was a humming or buzzing noise coming from the magneto which was audible with the engine running. The mag is a Fairbanks Morse K4B4A rather than the J4B3 which I am used to seeing. It is a bit bigger and is the cleanest, shiniest magneto I have ever personally seen, it looks like the pictures of reman ones I see online. When I put my hand on the mag case it seemed to be vibrating but I could not tell if it was vibrating more than the rest of the engine. I would have thought the sound was a water pump bearing going bad but with no fan belt that didn't seem possible. The sound did seem to be coming from the mag area but I could have been wrong. I only ran it for a couple of minutes and then shut it down. Any advice will be much appreciated.
