Nice find!!
From what I remember about them "ZINGERS" they have a small exhaust port out of the head. I think we use to remove the exhaust and scrape the soot out of the jug to open the pipe back up. They would act like the exhaust was plugged and they would not start.
That would be my first thing to check to get it running.
