Which Lycoming is that?
I was wondering the same thing. I can't make out the model # on the photo of the data plate, but it it looks like it says it's rated at 95 hp @ 2200 rpm. The old FAA registration data for that Starduster lists engine make/model as Lycoming 41506. The FAA's listing of Lycoming engine codes says the #41506 is an O-290 of 140 hp. I wonder if this is actually an O-290-G that was derated in it's original configuration.

Almost certainly a -G, you can see the reinforcing plates on the crankshaft flange. 95HP @ 2200 is odd though, the -D curves show about 113HP at 2200. But it's gotta be a real old one with the 73 minimum octane on the data plate. Looks like it crashed twice, once in 1976 and again in 1988. Been gathering dust for a long while...
