Ernie,
First of all, our home airport is at 5500' and I've never seen a 12,000'DA day.
My experience is there is no need to worry about the mixture on a high and hot
day with these engines. Of course, you can easily be over rich on taxi, but
I've never experienced an engine wanting to quit do to flooding at full power.
If you do feel the engine shuddering on take off, you are at full throttle
and can easily adjust the mixture leaner to smooth things out, even if the plane
still has the obnoxious tab on the mixture control.
Again, I've flown multiple stock CJ's on high DA days without any issues. Your
climb performance, however, is gonna be less than stellar. Oh, and there's also
these big things we call "rocks" that you need to worry about. [Wink]
Hope this helps.
Cheers,
Barry [Laughing] [Wink] [Wink] [Wink]

Hi Ernie,
First of all the mixture stop should have been removed a long time ago. US fuel
and long taxi times (if you're a formation pilot) with a stock Housai setup guarantee
carboned-up and gunked up engines with the original mixture stop. You
need to go nearly full lean on a stock Housai while taxiing for engine performance.
I've taken off from Big Bear on a 9,500ft DA day with my Housai and I found that
it would lean surge if I did anything non-standard other than maybe one or two
clicks forward. With a normal Housai setup, the full-rich is WAY rich and full
lean is running but will surge.
Typical for me, takeoff with a Housai is not full-rich but for higher altitudes
but only a little forward (lean) of full rich.

On my old CJ, I had the tab and liked it. I never had carbon foul problems
with mine, but again, I live at sea level. About 90% of my flying was done
below 4000 ft and I rarely touched the mixture control. Flew it full rich
all the time.

Hi
Update on the prop.
According to the prop shop the one blade is quite a bit heavier than the other
one.
If any one has got some type of diagram on how to add weight in the blades
I would appreciate it
Thanks
