Bill,
I found your comments quite interesting, and also very much on
target. It is very easy to forget the
simple stuff. My background is on the
electrical / electronic. Currently work
as a data network engineer, after years of technical management. Though I have worked on motorcycles over the
years, and do quite a bit of car maintenance, rebuilding, and adapting the
rotary for aircraft use, is definitely my biggest mechanical project. Well, not counting building an airplane in
the first place.
I know my limitations in the mechanical realm, and take all helpful
hints and suggestions.
Regards,
Steve Brooks

Steve,
Please
understand that I was NOT trying to be critical of your efforts. You did
perform the MOST important part of the repair, you actually fixed the problem!
I mentioned the old tech training comments because we ALL tend to bypass the
simple problems. (To all of our peril.) I just like to remind everyone to look
through the basics first when encountering these problems. It will often cut
short your repairs because you find the simple problem. If you don't find a
simple problem you are still ahead because you KNOW that you haven't forgotten
everything. It is amazing how even successful people often start in the middle,
mechanics wise. Some time I'll tell the story of the very successful 2 stroke
tuners that wouldn't believe us when we told them that the charge in a 2 stroke
engine went UNDER the piston and into the crankcase first! These guys were
building race-winning engines! They must have had a BIG pile of cut-and-try
cylinders behind their shop!
Cheers, happy
flying!

Bill,
The spark plug without the conductor would
definitely be a strange one. I do
sometimes overlook the simple stuff. I
always assume that it’s got to be something harder than what it usually turns
out to be.
The good news is, that I know for a fact
that a lot of things on the engine are in tip-top shape, after checking a lot
of different things trying to find it.
A few new electrical connectors.
Cleaned the injector connectors, etc, etc.
Regards,
Steve

While the turbo is at the shop, I'm going to pressurize the
cooling system,
just to make sure that I don't have any other leaks. That way once the
turbo comes back (3-4 weeks) I'll be all set to go.
Thanks for all of the suggestions.

Steve,
You
have shown people on the list TWO of the items that were drummed into all of
the Kawasaki technical training students when I was there. (A long time ago,
probably before dirt!)
1)
Check the simple stuff first! (If the engine won't run check for gas in the
fuel tank BEFORE any other check is made!)
2) If
it was running well and you changed something and then it doesn't run well find
out what you messed up.
Not
doing these things was grounds for failure. After checking the basics then
continue downhill from there in a logical fashion. Some of the problems we gave
candidates were diabolical, (clear nail polish on the spark plugs for
instance), but instructive. Later these mantras saved me when a spark plug came
from NGK that looked perfect, but lacked the copper core conductor. A
production line fault. It doesn't happen often but it can happen. Glad that you
were able to find both problems on the ground!
