Jabiru CHT temps high, on 2,4,6, but 1,3,5 OK.
All EGT OK.
I flew my new Zodiac for the first time today, It was great, except for the high CHT.
I had someone else fly it first, did my GA conversion and flew it today. I was told cyl 4 was too hot (170 C), so I installed a baffle in the ram air duct above cyl 4. (Jabiru 3300), The test are much cooler.
When I flew it cyl 6 was hottest.= the baffle cut air to 6.
I tried cutting off the lip on the cowl, and moving it back, made it slightly better, but still too hot.
It is running a bit rich, but I will leave that until run in,
I am thinking of cutting the exhaust pipe which extends about 8" past the cowl to a close fit, I am told that may help.
My next steps are to experiment with the cowl shape.
Any constructive ideas welcomed. Can;t wait to sort this so I get to the real flying.
