Terry,
Its going to be stormy here in Houston, so I'm going to the hanger.
In your last post you said you cruise 4800- 5200 rpms. That is about where my
EGTS start getting too hot. I believe you said you were running a 11 G 2
jet needle. One last question. What are your static rpms set at?

Ed,
My static rpm is about 6400. I swing a wood prop which doesn't allow
for any change. It was about 6200 rpm until I alter the prop tips to
make it quieter ( earlier discussion).
As far a EGT temps, I have the old service manual from Rotax which gives
specific numbers for EGT's and CHT's. You may already have this
information, but if not, here it is.
It states the upper limit values as such: CHT at spark plug seat -
450 F difference between two cylinders - 36 F
EGT
- 1200 F difference between two cylinders 45 F
As I stated before, I run EGT's from 1075 to 1190 depending, sometimes
pushing 1225 at higher altitudes. From what you wrote before on
2-10-08, I think your worrying about nothing. I would like to see what
would happen in your were able to borrow another EGT gauge and see what
goes. Also, our senders are not always accurate. I had a problem with
wiring connectors last year messing up my readings. Another test that
would be interesting would be to borrow another carburetor and see what
happens. Did that for a friend and what a surprise. Someone else
mentioned looking for an air leak. Might want to spray WD 40 around the
carb mounting rubber and manifold while running. Blue smoke will let
you know if you have one.
As my friend and 2 cycle Guru keeps telling me, over and over again,
look at your plugs and cylinder tops and you can tell whats going on.
He tells me not to chase the gauges. Of course you have to learn what
to look for! Also, if you take off your exhaust Y once a year you can
observe what's happening in there and if your rings are free.
Yes, I'm using the 11G2 needle, but that is for mid range performance
and I don't think it will solve your problem. Got that idea from the
list years ago! Can't remember the gentleman's name, sorry! I may
have to change again when the Ethanol "monster" strikes here!!!!
Good luck with your trouble shooting,
Terry - FireFly #95

The draft can be stopped easily by cutting a7inch circle out of 4in foam rubber
on a band saw,and cutting appropriate slots for the cables and stuffing it in
the tube at the rear end.My highly modified exhaust system on the Mk3w/jabiru
was gassing me until that modification.

-speaking of the cables in the big pipe; it occurs to me that I
haven't done an inspection yet of the
spot where they intersect. I remember when I hooked them up, trying
to figure a way to avoid
the situation. I consider it to be the weakest point in the MkIII
design even if it never causes any
problem. I did think about using a piece of clear vinyl tubing
sleeve but the cable ends were on by
then and I wanted to go flying.

Terry,
My plugs are white with a hint of tan. I take that to indicate a lean
condition! I think my gauges are somewhat accurate. When the egt gauge reads
1200+ the engine starts running rough. When I pull out the enrichener the
engine smoothes out and the egts drop. When the weather clears I am going to
put back the stock jets and put in a little more pitch. It will be warm weather
here before long and that will make things a little richer also. I did a
de -carbon at 50 hrs and now have 78 hours on it!

| Subject: | Finally flying my MK III!!! |
After a long wait I finally got to fly my mark III today. What a nice flying airplane!
Its amazing how much different it is in yaw stability vs a challenger
II. My instructor helped me get a lot of little things checked and fixed before
flying. I got down there to his airport (2.25 hour drive) at 10 am and we finally
finished a little after 4pm. He flew it at 4:30 to give it an initial check
and by 5:30 I took my 1st flight in it with him!
The 503 performed very well just as good as his challenger. The Kolb will cruise
nicely at 50 to 55mph at 5 to 5500 rpms..
Indicated stall speed seems a bit higher than i though it would be. Empty weight
on the plane is 425# + me 150+ instructor 165+ fuel 60= 800# gross
Indicated power off stall was around 43 mph clean no flaps. Does that sound about
right? temp today was about 75 degrees elevation 185 MSL
Solo stall speed was about 41mph with a gross of about 700#. The plane has to have
at least 195# in the seat to be within the W/B.
What kind of indicated stall speed are you all getting?
All in all I had a great time! I really like the Kolb! Landing is a tad tricky
with the tail wheel but takeoffs are very easy.

Grant I will give you the same advice that Travis at TNK gave me when I was
bending gear legs with great regularity. Learn to wheel land it like a sail
plane and you'll find it's the sweetest landing airplane, tailwheel or no.
Once you get that down you can start learning to three point it if you want,
but you really should learn the wheel landing first. Just my opinion, but I
have the hydraulic press time straightening landing gear legs to back it up.

Russ,
I checked the MSDS for Bon Ami. It contains calcium carbonate, sodium carbonate
and some amount of feldspar. The feldspars are a very broad family of minerals,
but they have one thing in common. They are all silicates.
Here is a link to the info I looked at:

Grant,
Your experience with the higher stall speeds is normal. Adding VG's to your Kolb
will get that stall speed down to where you want it. I had close to the same
stall speeds with my MK III Xtra, which is much heavier than yours, and putting
VG's on it made a new airplane out of it, not just in stall speed, but the
way it felt throughout the lower speed range. Below is a shot of my panel during
slow, right on the edge of stall, level flight.
I put about 140 VG's on my wings, from the center right out to the very tips of
the wings. Its critical to install them very precisely, but if you do you will
be well rewarded.

If the chassis is not damaged, Just get a big rubber hammer, pound the aluminum
sheeting out, and reinforce the structure with some 4X4's [Wink] It would
look funny, well maybe horrible, but you would have something to tow your firefly
in.
