You might also note that a lot of Jabiru engines will have some head bolts keep moving for up to the first 100 hours. That was my observation. I carefully monitored CHTs and do believe they we ...

Actually, I had a Jabiru 3300 and had the same problem. Even with
everything well sealed in the engine area, it was a problem. I found all

Tim,
I take it you don't have cables to the rudder yet as there is a
