Agreeing with Motorman, I'm also puzzled by the high consumption.
After a thorough run in (around an hour and a half), my Aero Tiger, mounted on the prototype Brodak P-40 profile, required just a tad over 4 ounces for the pattern. After the clover leaf, I could fly an additional 5 to 6 laps.
I was using Brodak 10/23, 50-50 fuel, a plastic clunk tank, a 10 1/2 - 4 wood prop and 60 foot eye to eye lines.
