3300A
There seems to be a difference of opion here. My jabiru has a model 64 carb
and turning the mixture screw out will let more air (thus a leaner mixture)
and in makes the mixture richer.
See page 17 of the Bing manual

Tex,
You are partly right. The very early Jabiru engines had the Bing 64. I was not
aware there were any of those still flying.
The reference you made from the Bing Manual must be about the Bing 54 carbs, which
indeed does operate the way you describe. In the attached excerpt from the
manual on Bing 64, it clearly states that turning the idle mixture screw ccw
(anit-clockwise) richens the idle mixture. This is the same on all of Bing's
CV carbs including the Bing 64 and 94 series.

Tex,
You may be the only owner I've ever talked to that has a idle mixture screw
that controls the air. All idle mixture screws on all Bing carbs I've ever
seen on Jabiru engines control the fuel flow to the idle circuit. Turning
the screw out (counter clockwise) will increase fuel flow giving richer
mixture.

Greetings from Idaho, another state with large temperature fluctuations.
Do you have any photos of your cooler installation & cowling modifications?
Thanks, Mack

You'll notice I had to cut the bottom off of the cowl around the cooler to get
the coil cooler to fit. This was kind of dumb and only made for more glasswork.
A nice clean slice down both sites with a pice of scap aluminum and a few
temp rivets to hold in place (spreading it about 3/4") works well untill the
glass cures.If you slice all the way down both sides all you need to do is pry
it appart lightly. And the oval opening will remain symetrical. Hindsight though.
I'm sure each install and fitting of the cowling is slightly different.
I've heard reports from some that they didn't have to modify the cowl at all,
but then the oil cooler inlet still remains the same size which probably doesn't
make it as effective as it could be. This has produced nothing but positive
results for me.
