<p>Has anyone with a CH750 and a Jabiru 3300 and Sensenich ground adjustable prop re-jetted the carb? I am about to go through the process described in the Jabiru/Bing tuning guide, setting prop pitch to get proper EGTs. At the moment, they are too hot, and RPM is too high. Specifically, I am getting 3100 RPM in climb, and 1450+ EGTs. Some redline. Per a call to Jabiru USA, my target in climb for this aircraft should be 2950; per the tuning guide, EGTs should be 1225. </p>

<p>Anyway, before I start that process, I was curious if people running that same combination stuck with the stock jets, or had to re-jet. At this moment, I have a 2.85 needle jet and a 255 main jet. </p>
