I found a video which shows exactly how to do this, hope it helps anyone else who comes along here:

A variation on the technique as 90cummins describes in post #321!

I wouldn稚 go beating on the generator field unit.
Pushing it off is the proper procedure.

I'll keep working on this, but in the meantime, do you guys have a place to order parts from for these engines?

I got a gasket set through eBay. Here's one, there's several on there. I chose to order one that shipped from the US so it arrived quicker.

I got it all apart.
The armature (rotor) came out quite easily, I couldn't find a rod that would fit right, so I whacked it with a rubber mallet a few times and it popped off without much of a fight, soaking in pb blaster for a few days helped too I'm sure.
I then pulled the valve cover off, cylinder head, everything looks clean, no visible damage of any sort, very little carbon buildup, no scoring on cylinder walls, no play in anything.
I didn't open up the crankcase, I'm not sure I should since I don't see anything wrong on the top end, but I'd like to hear some opinions from the experts.

Here are a few pics of what everything looks like.

seems the rest of my pictures are having a hard time uploading, I'll try again a in a bit

If I had it torn down this far I’d open it up.
Pull the piston & check the rod bearing then there are no questions.
Carbon buildup in the ring lands can cause issues better to check now then to go back later.

Hi All -

Has anyone got torque specs for these engines? Connecting rod, crankcase cover, head bolts, etc?

Thank you!

Looks like it will be a while before my gasket kit gets here, so I might as well tear the whole thing down and check it all over. I'll post more pictures once I get down into it.
