Thanks for the pic, Bob.
I have been thinking of replacing my fixed pitched Sensenich on my
Jab3300/Zodiac XL with a Sensenich Adjustable.
How easy/hard is it to change the pitch on the prop?

Well, try this one on for size:
I have had to adjust my valve clearance several times recently, and
when I did it a few days ago, I found brass-colored metallic
particles inside one of the valve covers. I removed the oil filter
and cut it apart and found a few specks of the same material in the
filter. I removed the rocker shaft from the head to inspect the
rocker arm bushings, and found them in very poor shape, having lost
their teflon coating on the bottom of the bushing, and exposing the
sintered brass backing. The shafts are in good shape, slightly
discolored, but not worn.
Anybody else have a problem with valve lash? If you do, there's a
good chance that the bushings are worn, causing the lash to increase.
I did some research on the bushings, and found that they will
withstand over 400 degrees F, but could find no specs on how much
pressure the bushings will endure.

Lynn, nice to hear a voice or two on this list. How many hours on that
engine and what oil have you been using? (I have only 25hours but counting)

What prompted you to check ? Noisy, or was it a routine check. Keep it
going.

I've been here since day one, but have held off posting much of
anything on this group (I also watch the Yahoo one) until now...lack
of anything to write about. But I've got a couple of issues to talk
about...more later.
I've got about 280 hours on it since it was first flown about 13
months ago. I used the mineral oil break-in oil recommended, then
switched to Aeroshell 100W after that. During the winter I used
Aeroshell 15W-50. I've always changed the oil at 25-30 hours, with
the filter.
I enjoy the engine very much, and try not to bad-mouth it, but
recently I've had a couple of disturbing incidents. Anybody looked
inside their distributor caps lately?

After just the suggested checking at the proscribed hour, and
checking during the suggested head torque period, it came to me that
the engine was running more roughly...vibrating, actually...and
knowing engines as I do, I knew this could be caused by a cylinder
being off on valve lash. (If cylinders are dissimilar in their valve
lash, the power output is affected, hence it runs rough or vibrates.
It's a whole lot more noticeable on a 4-cylinder than on a higher
number of cylinders) After a lash re-setting, the engine ran fine.
When I found the brassy-colored particles the other day, inside the
rocker cover, and then "fingering" the rocker arms for slop, I
decided to pull the rocker shafts and have a look at the bushings.
What I found was a loss of the teflon coating where the arm contacts
the rocker shaft. I took the parts to an engine-knowledgeable person
locally, and he immediately recognized the bearing material as a DU
bearing material...do a google search for DU and read the interesting
history about this technology.
When I contacted my dealer, he said that apparently there is no
problem in the history of the Jabiru line of engines.
Perhaps there is no problem, but I've seen what my bearings look like
and I don't like the looks, and will be changing bushings soon. Since
I am out of warranty, I don't expect Jabiru to do anything for me, so
I'm taking the repair into my own hands.

I got a vast improvement in smooth running when I had my wooden prop
dynamically balanced even though I had spent hours to achieve a perfect
static balance. When the dynamic weights were added it was like a new
engine.

Did you try emailing the factory rather than the dealer about this problem?
