Last year I saw John Mohr perform his aerobatic routine at Oshkosh in a stock 220hp Stearman. I was amazed with how long the R-670would run inverted with the stock carb and no inverted systems.
I was wondering if anyone could shed some light on how this is possible? Is it something unique to the NA-R6G carburetor?
Thanks,
Glenn
