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.

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. Gary ----- Original Message ----- From: Tex Mantell To: lightning-list@matronics.com Sent: Thursday, July 03, 2008 5:49 PM Subject: Re: Lightning-List: rotating the carb 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.

I want to try to incorperate both the tie down and a jack pad at each wing. Also I want to keep it recessed or flush with the wing as each little item has drag . Has anyone have any new ideas on this to share? Tex ________________________________ Message 5 _____________________________________ Time: 06:17:52 PM PST US From: "Peter and Jan Disher" Subject: Re: Lightning-List: Tie down and jack point Hi Tex, A good Idea from Buz is to use steel angle and weld the nuts to the angles whereby you can screw the eye bolt into the wing only when needed, you would not then drag the eye bolt through the wind.

I'm going to use it too. I thought about making fairings in front of the islets for drag, but, if they could be recessed, that would be better. Anyone have an idea how? Also, how do you make jack pads on the wings? Thanks everyone.
