The engine ran hot and couldn't get much help from my lame. It wasn't till I found someone else that I got a solution but it was already on a downhill path.
He put a larger jet to richen the mixture, filed down the baffles a fraction to improve airflow and voila, the temps dropped 50C or more.
Unfortunately the heads are warped and leaking oil and I could get a rebuild but the estimate for that from Jabiru is quit high for a low hours engine. It's an early hydraulic lifter,
I ran the engine according to the POH and it is my first plane so a lot of learning in the process.
