Actually, there are a few documented instances where the pressed Rotax
cranks have slipped, slightly, throwing the piston timing off enough to
cause vibrations. Granted, this is the exception, but it does exist...

Lots of good stuff. Thanks John and Gilles and others.
One thing about Jabiru installation perplexes me: Every Jabiru
installation I have looked at over the years has had presumed cooling
issues addressed with little deflectors inside the cooling cowl which is
part of the engine package.
This is heartening since it shows they (Jabiru) have been paying
attention. The perplexing thing is: why is there no provision for
inter-cylinder baffling? Every air cooled engine I've ever seen has
these. (Lycoming, Continental, Franklin, de Haviland, Ranger, LOM, P&W,
VW, Porsche... all except Jabiru, free air or fan cooled.
Not only for cylinder and head temps, but for cooling drag reduction it
is a good thing to make all the air entering the cowling do good,
efficient work removing heat from the engine.
Why? What am I/we missing? Jabiru installations have huge passages
between cylinders and heads so a lot of air rushes through (because
there's less resistance) rather than being directed through the head and
cylinder finning.
I also agree that the Jabiru would benefit enormously from a 6-point
fuel injection system. Or perhaps 2 of the Rotec "injectors". It is
really hard to evenly distribute the relatively large fuel droplets
emerging from the Bing's mainjet well through the Jabiru's long,
serpentine induction passages. Liquid doesn't go around corners, it
sheets out on the outside of bends and crawls downstream.
The major users of diaphragm (constant velocity) carbs, (Bing, Mikuni,
Keihin) are motorcycles and outboards and they are mounted on a straight
through manifold as close to the intake valve as practicable. Not the
case on Rotax or, especially, Jabiru.
Sorry for the verbosity.

I read with interest the thread about 'burping' the engine (shades of new
grandchild). I wonder if this applies to 914's as well, since many facets
are common to both?

the 914?
Hi! Ferg.
Yes it does, since the oil always drains in to the sump. Burping it gets
the oil pump primed full of oil and all scavenged away to the tank and so
ensures hydraulic push rods earliest oil pressure is achieved on start up.
It also primes the carbs with some fuel vapour. Not withstanding .."no burp"
.no oil or bust pipe or pump and that's the best time to find it !!.
To prop the engine (mags off!) also gives you a distinct "feel" of any
lacking cylinder compression.
That's why I do mine myself.
Regards and Happy New Year.

| Subject: | Help with MDO Aircraft Wheels & Brakes in France |
Europaphiles & Gilles,
I would like to purchase the "MAITRE CYLINDRE DE FREIN <AU MANCHE> from MDO Aircraft
wheels and brakes, 40 Rue Barchalot, 64200 BIARRitZ. I have contacted
Mr. Denis Bastein and received a reply but after promising to send the complete
brake setup for the Europa within two weeks back in November, I have heard nothing
since. He no longer responds to my e-mail.
I would greatly appreciate assistance from anyone in Europe, especially France,
in the purchase of this devise configured for the Europa. If you have to purchase
it for me I can arrange for transfer of the necessary funds or allow charge
to my Pay Pal account.
Thanks in advance,
Bob Borger

I'm just about ready to order the material for the sub panels to carry
the instruments in the panel molding. Any guidance on material
specification and thickness would be helpful

My panel is built from .063" aluminum. Very ridged and light weight.
Available at sign suppliers.
