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.

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.

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.

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 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=423087#423087 ________________________________ Message 5 _____________________________________ Time: 04:20:23 PM PST US Subject: Yak-List: Re: CJ HELP Need A Prop Nut Socket to Buy, Rent, Borrow From: "dbotich" Thank you all.
