Oh yeah, big time...
I'm getting ahead of myself as I wait for a response here, but as per this post, it could be a ruptured fuel pump diaphragm. Could I have accidentally done that while blowing compressed air from the inlet side to clean it out earlier? That wouldn't explain the burning of the oil though, would it...

Was the oil level over full? Yes it could. The gas would thin down the oil and allow it past the rings much more.

Drain the oil, pronto. It will also be a good idea to service the oil pressure relief valve to make sure it's doing its job, as described in these two threads: thread 1, thread 2.

You likely didn't ruin the fuel pump with compressed air; it probably just failed on its own; that's a thing.

Put in a new fuel pump. Pick carefully; parts-store items currently available are garbage. Get an AC 6972; one of the ones you see here.

And show us those spark plugs.

Yes!

I've been too pressed for time, and I'll be away from the vehicle for a bit... Couldn't get those pics yet since waiting on a friend for the socket after mine disappeared.
I won't let it run with that fuel oil invasion, but not much I can do right now other than let it sit for the time being while I'm away.
Quite the coincidence, same time as the carb rebuild.

Will order a new pump for when I get back. Rebuilt is okay in this instance? (e.g.)

I know the as-built AC pumps do okeh with curent fuel formulations. No way to know if the rebuilts will, until you try. Odds are pretty good.

Also, to be clear: new oil filter along with new oil.
