So far, I haven't been able to establish any such link, but the mention of the diverter
got me thinking and looking. During the recent work I did, one
thing that I changer was the location of an adel clamp that supports an oil line than runs
just under the carb. It;s new location makes use
of the same bolt that affixes that diverter. Looking inside with a mirror, I can't really
tell if it got canted at all when I removed and
replaced it's bolt, and I haven't yet disassembled the diverter to see if it actually
*can* physically twist, but maybe, just maybe, that's
what happened. Not sure why just the center cylinder in the bank would show the effect,
but that's probably a fluid dynamics exercise ;')
Anyway, I'm thinking to make the diverter change you mentioned, but so far have not found
the article/SB. I've checked the SBs on jabiru.net.au, but don't
find it there. If anyone can provide me a link to that information, and/or experienced
instructions, I'd appreciate it. Thanks, as always.

It's VERY highly unlikely that loosening that bolt, or even removing
it completely would allow the diverter to get out of place....that
is, if it's anything like the "manifold" that WAS in my 2200. In the
2200, the manifold halves are machined to accept the shape (teardrop)
of that diverter, and unless you had *all* of the manifold-attaching
bolts loosened by at least 1/8", the diverter would stay in place.
That is, IF the 3300 uses the same *type* of machining that the 2200
does/did. But as we all know, or should know by now, Jabiru makes
changes without consulting me (that's a joke, for those humor-
challenged folks out there), and the newer engines could be different
from what mine was.

Oh, OK, haven't actually taken it apart yet, so I'll take your word for it. Do you happen
to know any details of the 1/2" ring/tube/rod
mod? Realistically, I'll prolly just put the carb back on and experiment with tilting it
slightly off vertical, but the divider mod is
intriguing...
Thanks, Lynn.

I talked to Pete a couple of years ago, and he said that Jabiru had
played with different shapes for that diverter...round, square,
teardrop, etc., and finally settled on the teardrop. But later
stories have had people having success with the round one. I have my
old manifold in the shop, just measured it, and you have to split the
manifold by about 90 thousandths in order to get the diverter out.
Mine is 1.337" long, and is threaded .988" deep. It doesn't have to
be threaded that deep, just deep enough to accept the length of the
1/4-20 cap screw that holds it in place. On my manifold, the screw
goes only into the diverter piece...not through it and into the other/
upper side of the manifold. The diameter of the tube/rod would have
to be 0.472" give or take a thou or two, in order to sit into the
seat that is machined into the manifold.
The manifold halves are aligned with approx. 1/16" diameter dowel
pins....maybe they are 1.5-2 mm's....not sure of this because I
didn't pull the manifold completely apart just now. It would be kinda
tricky getting the manifold apart while it is still on the engine,
but it could be done if you were careful. Whatever you do, don't try
sticking a screwdriver into the split around the manifold, because
you'll bugger up the machined surfaces. It seems to me like it would
be better to remove the manifold and intake tube lower sections in
oder to do the job right, because you have to replace the o-rings,
and scrape off all the sealer that has been applied around the intake
tubes...at least it was applied on my engine.

Thanks, Lynn. Sounds like a bigger job than I had in mind. Think I'll wait on that, play
with tilting the carb slightly.

Yes, changing out the diverter would involve a bit of work.
On tilting/rotating the carb, I made up a small pointer and attached
it to the spider as I recall, then made a mark on the top of the carb
at the starting point. This way I could tell exactly where I started
from, and where I was going to, with respect to carb rotation. It
doesn't take much, and without a "fix" it's hard to tell where you are.
Thanks for the prop specs....my friend has a Waiex w/3300 Jab, and
his is 54 x 64 Sensenich.

I went with Lonnie's recommendation, and I'm happy with it. I see about 3150 WOT
full rich in flight, but there are a few variables that can come into play
there, not the least of which is carb tuning...

Lynn,
the 3300 has a similar arrangement for the plenum, except the bolt that holds the flow divider goes all the way through into the crankcase. Given that the intake tubes are sealed with O-rings where they exit the plenum, you would have to wonder why there is sealing compound around the outside as well. There was on mine and it had gone hard and cracked. Doesn't seem to be a lot of rhyme or reason for some of this stuff. Maybe just that a whole lot of different people have tried solving issues at the factory level.

Sounds like the old belt AND suspenders, eh? Yes, my engine also had
the o-rings and goop applied. And it's probably little wonder that
the tube-to-manifold seal is a bit tricky to seal....those stainless
steel intake tubes can't really be all that accurately bent, I
wouldn't think. Mine was sealed with something that was similar to RTV.

the 3300 has a similar arrangement for the plenum, except the bolt

sealing compound around the outside as well. There was on mine and
it had gone hard and cracked. Doesn't seem to be a lot of rhyme or
reason for some of this stuff. Maybe just that a whole lot of
different people have tried solving issues at the factory level.

Do you suppose the goop is just used to help slip the pipes in? Vaseline would be as good but maybe the extra stiction is a good thing.

I visited the Jabiru factory at Bundaberg - Great bunch there - all very helpful - learnt a lot about the different sealers used in the engine. The black "Gook" is worth putting on the inlet tubes as any leaks there will lean out the mixture.
Cheers
Keith

Thanks Keith. I just love these words. Goop, gook, stiction. Just so descriptive.
