I'm new to the Jabiru Engine list, and have just acquired a 601 XL with
a 3300A Jabiru Engine, Serial # 33A641. The plane still has 14 hours of
its mandated 40 to be flown off in the Houston, TX, area. Can other
XL/Jabiru 3300A owners give me an idea of their CHTs? This airplane is
showing 366F on the number 6 cylinder, Grand Rapids EIS. The builder
added the carburetor economy change. The plane has the standard
Zenith/Jabiru FWF cowling and 'air leaks' have been plugged with foam.
It has the carbon Sensenich prop. The high temp does not occur during
climb out but when throttled back to ~2750 and also does not cool down
on descent/approach for landing. As I am about 1500 miles from the plane
at this time, I retained an A&P to attempt to resolve the issue through
baffling. The previous owner/builder tried relocating the carburetor
slightly at the suggestion of Jabiru, and has played with baffling to no
avail. I am aware that at approximately 26 to 30 hours run time that the
engine may not be fully broken in. Oil change and re-torque of the heads
occurred at 25 hours. I would appreciate any information XL/Jab owners
might have regarding their maximum CHT temps, especially #6.
Along the same line, have any 3300A owners gone to an AeroCarb over the
Bing for mixture control/lower EGT/CHT Temps?
Thanks,
Ed

Hi Ed,
Just checking to see how you made out with the Aerocarb as I am also chasing a leaner mixture at the bigger throttle openings?
