23 liters for the 3300cc Jairu is conservative. My 80hp 2200cc Jabiru
uses only 13 liters per hour at 2500rpm cruise revs.

Thank you, this is kind of useful information.
In what aircraft, please?

A fellow by the name of Kerry Fores did some test flights to evaluate
the fuel consumption of his Sonex with the 3300. I believe it was
equipped with an Aerocarb. The results IMHO are quite amazing. If his
results are accurate with the 3300, I'd like to know what the results
would be with an Aerocarb equipped 2200. I got his article off the
Sonex website. I'll try to send the URL.

I think the key is the Aerocarb. You can manually lean those. I
believe the Bing carb the 3300 normally comes with has a set mixture
(approximately rich of peak). That and the Sonex has pretty decent
mph/hp
