Jose,
Get JSB018-2 from the Jabiru site, it shows what jets should be
installed. If you have the economy kit installed then your needle jet is
too small. Standard is 290. That could well explain your hight EGT's. If
you do not have the economy kit installed, then check on page 4 what the
standard jets for your serial number are.

Jose,
I have changed carb jet size so often I can do it in place on the engine in about
20 minutes. After many combinations I came up with a 260 main jet and a 285
needle jet. My CHT's are running 270 to 315 but there are a few throttle settings
where they will climb higher.

Jose,
My experience is with the 3300. I would start by placing a very small
washer under the point where the needle sits in the slide to raise it, and
depending on what size main jet you presently have, I would go two sizes
larger. ( Say if it was #165 I would go at least to #170 or #175) Once you
have got the temps down and have bedded the engine in, then come back down
as necessary...
Make sure you check the float height too.

Jose, when you pull the top of the carb off to access the slide and remove
the needle, chances are that yours will only have one groove for the clip,
therefore no adjustment range. If there is more than one groove, move the
clip to the bottom groove. Otherwise hunt around for a thin washer that
will fit over the needle and no more than around a mm or say 0.040" and put
it between the slide and the needle clip so that it effectively raised the
position of the needle relative to the slide.
A lot easier and also reversible than buying other needles at this stage.
The main jet will require going bigger, but remember that these jets are
ofifice sizes, not flow rates, so if your main jet is stamped with #260, it
is actually 2.6mm. So you could buy a 2.7mm drill or reamer and do it
yourself.
Cheers
Marty

You only have 27PSI oil press. at 2840RPM ?? That to me is scary!
For what it's worth I run 285 needle jet, 245 main jet. This is a 2200 #2456 in
a Zenith 701. After things are sorted out, change oil and filter. What air speeds
are you cruising at?...DonB

out, change oil and filter. What air speeds are you cruising at?...DonB.-

Jose,
Assuming you are measuring the pressure at the "gallery" not at the
oil pump output as is often the case with Jabirus this is solvable. I
also have a 3300 and until I changed the oil filter adapter plate and
all the oil hoses I had the same low pressure. Now it sits at 40-45 PSI
under all conditions. Personally, I think some of the Jabiru problems
are caused by low oil pressure.
It this is the pressure at the oil pump (I believe the top hole)
then there is a real problem and should be fixed before further use as
the gallery pressure may be below 20.
