Well my engine RPM numbers aren't too low in comparison. But at the time I hadn't run more than a few tanks through the engine on a test stand. It has been running real good in my large low wing plane though. It could be he adjusted the static timing a little where I just left it as is from the factory. Maybe their gasoline is different than ours here, or they have more oxygen in the air than we do too.

Being a bit paranoid about the oil percentage in the fuel, I am running a little more oil in my engines though and that can affect the power output too.
