A few weeks ago I asked which way to rotate the  carb to possibly even out the egt's. It works. I now have the cht's within 30  degrees of each other and the egt's within 45 degrees of each other. I also  noted that after about  30 minutes at cruse they are almost even.   Tex

Gary, It is possible to rotate the carb a few degrees on  its mount by loosing the strap which holds it to the engine. By turning the  bottom of the carb towards the lean side of the engine ( indicated by the EGT  temps on that side)  will slightly richen the mixture being drawn thru the  Ventura to that side of the intake manifold. Fuel enters the system from a port  in the bottom of the carb. This is only a slight difference but can be helpful  in obtaining a more even mixture for all cylinders. I hope I have described this  correctly, if not someone can chime in.  Tex

Tex,

  

     Sounds like your engine is doing  great; I didn't realize that you had flown already.    Congratulations!  Please send us a picture of the whole plane.

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Hello again Tex

 Thank you for the explanation. I didn't realize it made a difference. I  thought the carb position was fixed and that all cylinders received equal  mixture. I have a lot to learn about the Jabiru.

 Hi Gary,

     Your words above are a good reminder for me to once  again suggest that everyone that is even thinking about using a Jabiru engine  should attend the engine seminar.  It is time and money well spent.

 Blue Skies,

 Buz

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]-->  Hey Buz

  

 I totally agree. I am planning to attend. I just haven't sent the  registration yet. Sure wish there was a seminar out here in Tucson, Arizona.  Airfare, lodging and car add about seven hundred dollars to the cost and I still  have to fly out there for the three hour transition training.
