The cooling tube mod came out after there was a high coil failure rate. This was
the different make of coils that are never used now.
I ran an infrared temperature check on my coils after flight, only the left side
behind cyl 4 was a little warm. seing that its directly behind the duct just
drilled a bleed hole in the duct for it.

Thanks Buz, Rick, Lynn and Ralph for your experience. That's the great thing about
forums like this. I think that I'll have a check on the critters after I'm
flying and monitor how cool, or not, they are and take it from there. Should
be an easy mod to do retrospectively.
I could spend the rest of my life modifying this and that but never end up flying
the thing!
Thanks again.
Ian

Homebuilt aircraft are never "done".
There will always be something to fix or improve. Thats the game we play...

And once you truly do stop finding stuff to fix/improve then it is time

| Subject: | cooling the ignition coils |
Hi All--
While perusing the recent correspondence about cooling the ignition coils with
blast tubes, another facet of cooling the coils came to mind. I recall reading
some time ago somewhere about Jabiru recommending using fiberglass washers on
the cooling coils to isolate them from engine block heat.
Now I can't find anything about that on the factory website (or anywhere else,
for that matter). I also have a question about where the washers would be installed.
On the outside of the coil under the bolt head wouldn't seem to be nearly
as effective as between the coil and the engine; yet that raises the question
of offsetting the alignment of the coils with the magnets on the periphery
of the flywheel.
Thoughts, anyone?

Alvie,
Between the coil and the engine is how my engine came and what I have
continued to use for the past 500 + hours. The alignment of the coil is not a
problem, but of course the gap between the coil and the magnet is critical,
especially for cold weather starting.
Blue Skies,

The fibre washers are indeed fitted between the coil and the engine.
There maybe washers under the head as well, I can't recall?
My 2200 doesn't have them where as my 3300 does, it's all about when the
engine was built. It's a good point about the alignment and although I
thought about it I haven't ever examined the difference. the washers are
quite thick. Maybe the engines with the washers fitted have a little
metal removed from the mount area so the alignment is still good. I
haven't retrofitted washers to my 2200 engine even though I heard about
it. On that I did lose a coil at 700 hours though the other of the pair
has now done 1060 hrs, neither engine has blast tubes (yet).
Maybe some one can have a look at an engine with washers? Be simple
enough to gain some clearance.
Regards, Clive

Ian,
Look at http://www.geocities.com/cffd66/Airplane/BlastTube.html to see how I
used 1/2" CPVC.
The one on the left coil is cut at a 45 degree towards the front to allow
the air to expand forward and cool the coil that is slightly forward of the
tube. I used JB Weld to cement the tubes in place.
