Ernest,
You're supposed to point the exhaust at the neighbor's house. ;-)

Mark

I'm still learning.

These numbers sound reasonable to me. Is this about what other builders are seeing?

I'm adding fuel across the board at the top end, and will expect a higher RPM tomorrow. The big race now is to get home from work and find a hole between the summer storms to roll the plane out, get a logging run and roll it back in before the lightening gets it. Last night, I got in a hurry and left both the garage door and inside door open. The house filled with exhaust fumes to the point that all the fire alarms started going off.

The wife was *NOT* happy with me. 8*)
