the Moki radials don't need MORE performance. Out of the box they'll pull rediculously pitched props. Mitch
Yes, well I don't need more power either, just want to see if it can give more power. And if it is now consuming more fuel, one would expect it would give more power. I suppose it could unload even bigger pitched props now in the air. Moreover, I felt that the lower cylinder at 5 O'clock is not cutting out the way it used to, meaning it is not so sensitive to the needle settings as before. Perhaps it gets better mixture there as well.
