Good numbers and obviously LOP hasn't caused any engine problems after 1900 hrs...

Ditto the kudos for continuing updates here.
Going back over previous year's posts, I noticed back in DEC 14, with your CF panel overlay, your abbreviated T/O and LAND checklist under the D-10 got dropped. That was one of my favorite "features"! Or, maybe it just got moved?

Check list
 
Doug,

It did not make the conversion - I will remedy that, pronto! Good call.

Pete,
You're numbers have always made me wonder what is "wrong" with my airplane. Then I add fuel and go fly and it is all better.

Year 12 Performance Runs
 
Got out and up today to see how the old girl is doing at cruise.

Cloudy, but 02degC and a pretty nice day. She seems to still have it at 12+ years and 2096 hours!

O-320, carb, dual EI, Hartzell, mogas. Otto flying the legs.

Yep - The D-10A has the dreaded black spot - it is stable for now, so I am just leaving it. The D-10A and the EMS-D10 have been great for 12 years and I know Dynon will fix me up when time comes.

The snapshot:



Data from the runs was pretty consistent:



I think I'll keep her!

You seem to have a very healthy engine at 2000+ hours...congrats! But your CHTs vary by quite a lot. Have you thought of making some changes to the baffling to even them out?

there seems to be some opportunity to even the CHT.

Steve and Doug,

Good catch! I even out the CHTs by applying partial carb heat. On the 3rd run yesterday I turned the carb heat off to see if it would make difference in speed or fuel flow(it did not).

My CHTs are usually within about 10-20deg of each other with the exception of #1 that will be a bit cooler.

I'll get a pic next time I am up.

With the corresponding low EGT it was looking like mixture distribution. Clever use of carb heat!! After 2000+ hours, it can't be that bad :rolleyes:
