Default My New PE-197

Just picked up this 1944 PE-197 generator from fellow member yellowlister. I plan on restoring it back to its 1944 glory. I would like to keep as much of the original OD paint as possible. But obviously I will have to repaint the shroud that goes over the engine and Generator. I plan on taking off the bracket that holds the battery and fuel tank. As you can see there is some Rust where the fuel tank sat. Luckily it did not rust the fuel tank at all.

Right now I have the fuel pump taking off to rebuild it. Turns out these are the same fuel pumps that were used on the World War II Jeeps. I took the starter off and cleaned the Bendix shaft and reinstalled it. I might give it a bath later on in the week to get some of the grease off.

I haven't tried starting it since I brought it to its new home. But I did manage to get it started today. It ran great although the engine wasn't idling at a constant RPM. The governor kept throttling the engine up. Might have to adjust the governor or clean the carburetor. If anybody has any suggestions please let me know. Here is a video of the engine running and a few photos I snapped today.

That's really neat! Love the radiator configuration.

Sounds like a clogged idle circuit in the carburetor to me.

Thanks Vanman. The radiator setup is definitely cool. I think I will go out and buy a can of carburetor cleaner and remove the carb later this week and clean it out.

Ran fine last time I ran it lol..can't remember when that was.. did you tighten the fuel bowl? I left it somewhat lose to let any fuel vapors out.. make sure you drain the fuel and carefully dry the float

I removed and disassembled the carb today and cleaned it with carb cleaner. I was also able to find an original set of float bowl gaskets. I also rebuilt the fuel pump today with a new diaphragm. Probably going to reinstall the stuff tomorrow and give it a try.

Today I cleaned the fuel tank out with some CLR and split washers to work as an abrasive and boy does it look new on the inside. I reinstalled the fuel pump and carb and ran the genny for about 20 min with no issues.

Does anybody know how the electronic choke works? Does it only work when you use the battery start?

It's both.. has a pull cable knob on the front.. I can't remember if it's electric or if it works from the heat from the manifold. It is a bimetal spring that pulls it in.. I remember I had mess with it a bit.. I'm sure it needs some attetion after 60 years

Sounds really good.. glad it went to a good home. When are you going to load test it?
