Section 8.3 of the revision to the 914 op manual dated nov 2002 gives a
figure of 20.4L or 5.4usg at 75% power and page 10.4 give 75% power as
5000rpm and 31" with a vp prop.

Hi all,
I was wondering how the correct air / fuel ratio is set for a 914. I
suspect that mine is running a bit rich. I see black soot on the cowling
and on the under side of the wing. I think that the fuel flows are on the
high side. I am seeing the following numbers.
- 4500' @ 30' x 5000 rpm = 6.2 US Gallons per hour.
- 4500' @ 28' x 5000 rpm = 5.5 US Gallons per hour
- 4500' @ 26' x 5000 rpm = 4.5 US Gallons per hour
I am also suspicious that it uses more fuel at the same power settings at
higher altitudes. I will connect my laptop to my EIS latter this week and
collect a larger data set to verify my measurements.
I'd appreciate anyone's opinion as to what I am seeing so far.
Thanks, Paul
