Hi Arnie, if it only had one hour on it when you bought it, you may as well be the builder. Nothing will be sorted. As far as stuff like vapor locks, I am a believer in sticking with the stock Bing carburetor. It works well, so why spend money to introduce problems?
Regarding high CHTs:
- Don't do a lot of ground running with a new engine. You can cook it in no time. Even a taxi will help keep it cool.
- The engine will run cooler as it wears in.
- The Sonex specified cooling air outlets are way too small. Download the Jabiru installation manual from their web site. https://jabiru.net.au/wp-content/uploads/2018/05/JEM3302-7_Inst.pdf It specifies outlets at least 3 times the size of the inlets. The Sonex outlets are about 1.5 times. You can get away with slightly smaller outlets on a Sonex because of the higher speed, but you really have to get the air flowing through there.
