Since the oil is up so high I would guess head gasket. I do not think the oil would be so high if it was a base gasket.
Maybe you see something I don't. In the picture I see a damp looking area going from the base gasket to the case screw (at one o'clock position to the case screw that is beneath the exhaust manifold). I can't see anything else in the picture.
They are not cut well from the factory, so they don't sit exactly right. Also when I was building my "do it your self" engine build I had to cut the top of the gasket off to get it to fit right because the gasket was one whole piece instead of the U shape that it really is.Replacing the base gasket is easy. I would do that and see if it stops the leak.
If not then it's the case gasket. I would like to know how/if you can do that safely. Mine looks either badly cut or wrongly positioned.
Correct. The leak is coming from the screw or some where near there. It is leaking so much it is making it up to the sixth cooling fin up from the base down the side of my reed valve all the to the back of the carb and almost all the way to the reed valve on clutch side. The base gasket seems to be completely dry on clutch side. Here's some more pics. Notice the "fresh" that im talking about and the "used" we are all used to seeing.Maybe you see something I don't.

Your money is on the reed??? What's that supposed to mean...Weird.... I didn't know it was way up on the cylinder fins too. I'm sure you will find it.
And my money is on the reed (but that's not real money).
I haven't gotten the chance to clean it up and check for it. But I sealed the reed valve to the jug so I know it's not there it must be base or case gaskets I think. There is no way the "fresh" oil could make it out the exhaust, right?I think the most visually obvious oil is o the fin.. Must surely have flowed forward along the cylinder cooling fin surface, from the interface of reed and cylinder.. Where you removed a spacer.
Someone mentioned that the fuel/air mix has velocity and the reed snaps shut.
It certainly can't be the head if it's unburnt fuel/oil.
Just thoughts.
If you clean it and run it, can you not see the fresh oil appear again?
