I called Jabiru Pacific and got some advice that seems pretty credible to me.
He told me to take the balance tube that goes from the carby to inside the air
filter and cut it down to 2 or 3 inches and turn it into a static port by drilling
4 holes in the tube 90 degrees apart from each other. Then to fly the plane
and test for the correct egts for climb and cruise. Then if jetting is needed
to go from there. I am not sure what difference there is from making it
a static port vs. being inside the air filter but I guess it is worth a shot.

...Thom,
Do you have any pix of the front of your baffle installation? Where is your BRS
rocket mounted? ...
I do now. See attached photo.
Went to the hangar today to replace the Bing jet needle with the Jabiru jet needle
for the 2200. It made a world of difference. My cruise EGTs with the Bing
needle were around 1225 and it topped 1350 on WOT climb, more or less the opposite
of what they should be. I swapped needles and changed main and needle jets
to the closest I had to what Jabiru recommends for this needle on a solid lifter
2200.
With 255 main jet (235 recommended) and 280 needle jet (as recommended) and Jabiru
needle, I get EGT of 1320-1330 at all cruise rpms below 2900. At 2900 and
above the EGT starts dropping. During climb, I can get to over 500' AGL at WOT
before the EGT starts climbing above 1250 and into the 1325 range. Lowering the
nose to raise the airspeed a little or backing off the throttle a bit gets
the EGTs back down to correct range. I'm perfectly content with the cruise EGT
but might go to a bit larger main jet to reduce the climb EGT. As a side benefit,
the climb RPM went up about 25 rpm and climb rate was up to 1200 fpm from
1100 before.

Because I will be looking for Kolbs, especially any MKIIIXs, at the Flying M Ranch
in Reklaw in October, I was wondering if anyone on this list will be there.
Here's the link if anyone is interested:

BTW, I've been following the Kolb with the Jabiru 2200 thread and have enjoyed
it. You guys are great.

Thanks Thom, good pic of the baffles. I will try to make something similar for
mine. I also already have close to the same jets I just need the needle, I will
go ahead and order one I think, and I will make sure I call Jabiru Pacific
for it.

I have been contemplating going to this since I bought the Kolbra and I am still
not sure if I will be there or not. I gues it depends on if I get all the kinks
worked out in time.
