To my amazement and relief, the battery charged up OK to test with. Cleaned a bunch of connections and now it cranks. The points look like they have been under water, but after cleaning them as best I could, it did fire a few times on starting fluid. Poured in some coolant and stopped for lunch. I'm pleased so far.

Looks like I'm going to get to do some ignition work. If I prime it with a bit of gasoline, it will start to run on all cylinders for about 2 seconds, then "putt, putt putt" on one, not making enough power to turn over on its own. This is a new one on me, I haven't seen that trick before.

At least the distributor is not hard to get to. No coolant leaking out so far - knock on wood.

After I went to the parts house after points, cap and rotor, the set "decided" it didn't need them right away. A few shots of gasoline down the carb to let it prime the fuel pump and it coughed, sputtered, popped and spit for a minute or so while I nursed the choke, then smoothed out and ran like it probably did when new. And it makes voltage according to my voltmeter, the panel meter is junk.

The workmanship in these old sets is remarkable compared to what we get today.

Need a video to hear that sound.

There is no way I would post a video of that start up, IF I had one. I will pass on some advice though - windshield de-icer will not work in place of starting fluid, even if the cans are the same shape and color.

I have not opened the generator end up, but so far it looks like it is not going to be easily reconnectable. The places I may use it will probably get by just fine with 120/208.

It might not be worth the bother, but I've torn into a 4-wire 120/208 generator and split the 'star' point open and re-connected it for 120/240 zig-zag. But 120/208, especially if you can crank it up to something like 127/220, is close enough...

Exclamation Disaster averted (maybe)

Found the governor full of stuff that looked like water with a little oil left in it.
A whitish-brown very thin liquid, whatever it is.

What can I "flush" the governor with to get it relatively clean before filling with oil? As most of you know, these governors are not common lately, so I should be careful with it.

Diesel fuel, WD-40 or ???
