| Subject: | 912 charing problem. |
Can someone walk me through diagnosing a charging problem? Last week my
volt meter was showing a charge between 25% and 50%. A couple days ago
I went out to fly around the pattern to see if I could figure out the
problem. On the ground it was showing 25% charge but in the air it was
down in the red with no charge. What steps do I need to take to
determine the cause?

Not an unusual problem usually requiring the replacement of the voltage regulator.
When mine failed it was intermittent, cutting short a trip in the back country
of Idaho. I got outa Dodge without delay and had a wingman along side until
reaching civilization, relatively, over Hailey. A 30-second conversation
with Lockwood got a quick response and a new regulator, not cheap, on the way.
No problem since.

Kirk,
Have you thought of maybe disconnecting your tanks and hooking in a temp to
see if the engine problem clears up?

Subject: Kitfox-List: Re-applying Kreem
Hello Kitfoxers again,
I think I am going to re-slosh my fuel tanks. Does anybody have a procedure
for this? The Kreem website is not specific to fiberglass tanks. They say to
leave acetone in a steel tank for 24 hours to dissolve old Kreem, then
re-coat with new Kreem. I think 24 hours would destroy a fiberglass tank.
Also, where does one get a gas cap that can be used in the sloshing process?
The reason I am going to re-slosh with new Kreem is that my Rotax 912 has
been rough running for 5 years now. For the last 14 months, the entire plane
was down with LEAF in southern WI. They tried everything to get this engine
running smooth. Eric Tucker himself looked at this engine several times and
he is stumped. I got the plane back, and started thinking of all the logical
things that this could be. Then I remembered seeing a black mist like
deposit on the inside of the intake manifold. LEAF said that it was just
from running auto gas and that auto gas is not as clean as av-gas. But, when
I asked some other Rotax service guy, he said that there should be nothing
but clean gas in the intake manifold. So, I googled the subject, and on a
boating website it stated that ethanol mixed with fiberglass fuel tanks can
produce a black misty like tar under the carb, and that you cannot see the
black mist in a fuel sample, nor will the filter stop it. Hence, I am going
to re-slosh my tanks.
I only use non-ethanol premium autogas, but you never know what you are
getting from the gas station.
Has anyone else seen any black mist-like deposits inside there intake
manifold?
Thanks,
Kirk Martenson

I am getting ready to install a door strut kit on my model II. I was
hoping to get some pictures and measurements from someone to simplify my
installation. Does anyone have some pic's and measurement I could use?
I am also interested in a possible back of door installation. Does
anyone have pictures etc for this?
Thanks,

You can use your same gas cap just wrap it in plastic wrap like you would food.
I have Kreem Weiss in my tanks like all the Flight Design CT's and most of us
use 91 octane with ethanol. Many CT's in the world use from 17%-24% ethanol and
no issues with Kreem Weiss. None of us has had any problems for 3 years. Kreem
Weiss is pretty impervious to just about anything. You may want to take another
look at some other component. I just re-sloshed a tank and only rinsed it
with acetone. Then just re-coat with the Kreem Weiss. Worked perfect. I have
been a Rotax service center for a while and the only black soot around the exhaust
is usually too rich a mixture.
I think I might do as Lloyd suggested and hook up an independent fuel supply first
and see if the problem continues. I just can't see it being the Kreem unless
there is something else in your tank.

I have some information now. Pictures later. First is the geometry.
Note that my struts are at the back of the door. The upper attachment
is 5.16" out the door, the lower is 13.66" down the frame tube. (Both
measured from the pivot centerline.) The strut centerline is offset 1
5/16" from the tube's centerlines. The gas strut is 8.5" long closed,
12" long fully extended, with a 4" throw.

These are drawings of my strut attachments. I bought the tabs and
balls from Guden and welded them to pieces of tube which were then
pop-riveted to the airframe and door frame. The pictures show the
tabs and struts bought from Guden.

I don't have any more pictures, for some reason, but will try to
remember to take some tomorrow.
