I've got a 74 x88 catto. The Co was a result of the band clamp not sealing completely, but I was going to change to 321 or Inconel any way, so I figured I'd do it now and be done with it. I wanted to be absolutely sure my timing was correct before going any further down the tunig road. I checked the timing yesterday, and I was getting the leading plug firing about 10 degrees in advance of those two timing marks lining up at 1400 rpm. I adjusted it so that it is now dead on at 1400 rpm. I set it there as a reference, it's easy to change in Mode 8. There's no reason to go any further in the tuning department unless I can be assured that the timing is correct. I've got a factory manual, but have not found any reference to the timng marks or exactly what they signify.

Brian,
Timing is one of the few things I didn't have to mess with. Once all the other problems were taken care of and the CAS was spaced correctly, the engine started and ran fine. What a day! I am using the EC-2 default setting for the renesis as programed by Tracy and have not even paid much attention to it or even checked it. Good luck on your next flight. I assume you are using the EM-2 and EC-2. What prop are you using? You make a good point on checking for CO. I just have one of those stick on cards and should borrow a real meter as I am running SS flex tube also.
