Marco,
THe small drop in oil tells me something not correct. Do you have a
rotax manual? It will show you to align the 2 marks on oil injection
pump.
Them make sure you get near full travle of the oil pump arm upwards
with throttle movement. ALso oil tank to be higher than pump and make
sure if flows by gravity. Pump is to be bled as well.
Here is a manual
http://www.ultralightnews.ca/rotax503/rotax2strokepdf/503installationmanual.pdf
Go to section 12.1 to find info.
Here is a few articles on oil injection
http://www.ultralightnews.com/alerts1/alert421.htm
article on oils http://www.ultralightnews.com/features/oiltest.htm
Hope this helps you all,
Kirby...... Ontario Canada.

Congrats yourself Greg! I know exactly the exhiliration you felt when that little
bird jumped into the air. Flying a cub does not compare. Interesting that #374
and 375 went airborne within a week of each other, 15 years after kits were
delivered.
I have adjusted the oil pump lever per the manual and bled air out of the oil line. Next fill ups will be 100:1 premix until I verify normal oil consumption. Theres a good article on Rotax oil injection system (and many other Rotax topics) at http://www.georgia-ultralights.com/page/page/898129.htm . I'm gonna hold off repitching the prop and rejetting the carbs to see what these adjustments to oil system do.
First flight pics will be posted soon. Thanks to everyone who responded.

Congrats on the first flight, Marco. I flew my mod. II for the first time
last weekend. What a blast! I have s/n 375, I've wondered how you were coming
along. As for the injection question, afraid I can't be of much help except to
say that the injection tank was already gone from mine when I bought it. So I
premix 50:1. Talking with some folks awhile back, they were of the opinion
that premixing was the way to go anyway. They cited the possibility of the
injection system going down in flight or running the reservoir dry. I haven't
heard of any problems with the injection on the 582's and given the usage rate
you describe, running the oil out doesn't seem very likely either, so,
there's my two cents worth. I wish I had learned to fly in the fox, it's a bit
like
starting all over again. The rudder? That's for turning the nose
wheel,right? : ) Anyway, congrats and enjoy your new 'fox.

Hey Ray,
Make sure they backpurge the muffler / tailpipe with
argon as they TIG the tailpipe back on or you'll be
replacing it again soon. The vibration on the
muffler will get all the tailpipes sooner or later.
I added a couple of 3/16" x 3/4" stainless supports
from the edge of the muffler at a 45 down to the
tailpipe and haven't had any further problems.

Ted

I have a request from Lister Robert Beck who just arrived in the Chicago
area from his home in Japan where he works. He has just over 300 hours on
his 582 and wants to send it out for rebuild to a shop as close to Chicago
as possible.
Can anyone recommend a shop for him? He will be in the USA until the 20th of
August so he has to work fast.

Hi Ray.
Been there. One of my biggest complaints wrt my Kitfox over the last four
years has been the muffler. It cracked several times in my first two years
of operation. I too run a 912S. Eventually I gave up trying tor repair
it and purchased a new exhaust system. I think my problem was related to
prop vibration, and the new prop is much smoother so maybe I am ok
now...but I also think the 912S high compression is a factor. I purchased
a DVD recently that has installation tips for the 912 series of A/C. In
the exhaust section..every sample installation showed the use of ball
joints. They insisted this was the only way to configure a reliable
system. Although some KF 912S operators seem to get away with their stock
Skystar exhaust systems, and so far my new exhaust has been trouble free
(but I have only 10 hrs on it ytd), I intend to install ball joints in the
very near future.

Subject: | Flaperons as Trim |
--> Kitfox-List message posted by: Guy Buchanan <bnn@nethere.com>
All,
I'm out on the web looking for a cool, light trim lever I can use
for my manual trim. I go to a Challenger ultralight site and see, under the
manual trim, the phrase "Not necessary if you have flaperons." So now I'm
wondering, do I need a manual trim? Should I just use the flaps for trim,
or is that draggy? I currently have the notched flap "upgrade" installed,
but maybe I should remove that, or modify it with some vernier capability
so I can use it as a trim. What do you think?
Thanks,
Guy Buchanan

You get 'sugar' on the back side of the weld that
weakens the weld and leaves it susceptable to
corrosion. Using the inert argon backfill during the
welding provides the same atmosphere as within the
arc field on the welded side.

Ted

I'm sure they'll know if they're used to doing SS.
Common practice. Sometimes folks not as interested
in reliability will shortcut and not do the right
thing. The weld will look fine, and last for a
while, but will eventually fail.
Good luck Ray,
Ted

Was going to purchase a couple of vacuum gages to sync the carbs on my
912S...then someone forwarded me a cheaper alternative. Basically you make
a manometer out of some tubing and a yard stick, with some oil in it.
Connected to both the carb vacuum ports, if they are not in sync the oil
moves away from the centre point. Not sure if anyone has tried this...but
from what I can see it would work fine.

Any auto part place shop that caters to sports cars, like English or
European ones sell a sync device called "Uni-Syn Model A". They been
in used for years and years and work fine on any multi carb setup. It
works on the principal of a small plastic bead that can be adjusted
to float in a tube. All you do is make both or all the carbs are the
same at all throttle settings. It can be adjusted for idle and part
throttle, and full throttle on small engines. Don't be snowed by the
hype the newer a better gadgets. Trust the engine tuners who have
used them for race cars to motorcycles and any other engine with more
than one carb.
I think you can find one on Google using "carburetor unisyn"

There is a skystar bulletin that says to add a bracket from the
pipe to the muffler.

Subject: | Re: Rotax Carb Sync |
--> Kitfox-List message posted by: Herbert R Gottelt <gofalke@sbcglobal.net>
I have been using a similar arrangement for years to check the sync of both carbs.
It really works great. I don't even use a yard stick. Make the loop long enough
for plenty of it to lie on the ground and comming up on both outsides of
the cowling. Attach one end to each fitting where the crossover tube from the
intake manifolds would connect. The crossover tube must be removed. Loosely tie
the oilfilled clear plastic tube together under the aircraft in a vertical
fashion. Without the engine running, the top of the oil in the tube should be
visible somewhere in the vertical part. It should have found it's own level and
both tops should be at the same level. After engine start, the carbs are syncronised
perfectly if the oil levels remain even to each other.

Connected to both the carb vacuum ports, if they are not in sync the oil
moves away from the centre point. Not sure if anyone has tried this...but
from what I can see it would work fine.
