I am running an ECI IO-360, Cerminil cylinders(group "A"), 9.5/1 pistons. 3.3 hours on engine so far. CHTs were in high 300s at beginning of first flight and were coming down to mid 300s by the end of that 30 minute flight. Running mineral oil for the first 5 hours, then switching to multi-weight oil.
The CHTs have stabilized at 325 degrees (cylinders 2-4 are all within 10 degrees of one another) and cylinder #1 is running at 285 degrees. The power setting is 25" MP/ 2500 RPM. I am planning on balancing the injector nozzles to bring up the #1 CHT.
Thoughts/ Comments? Is this engine broken in? It has burned less than 1/2 qt, and not burning any now.
