Oops, my mistake, Jim. I thought that "Home Builder Special" was an entire
tailwheel system but looking at Aircraft Spruce, I see that it is only the
tyre and that it could fit my Maule gear. I could have ordered it together
with the bushing.

How do you do that, Jim?

Mark, I think you have hit the nail on the head. I went and looked through
a pile of archives of things saved from this list over the years that I
thought might be usefull, and came across this:
"Per the Bing maintenance manual the enrichening circuit can be used
effectively to test mixture settings at cruise and max power: ease out the
enrichener knob, if engine accelerates then settings is too lean, if engine
stumbles the settings are too rich, if nothing happens then settings are
appropriate."
This morning I gave it a try. When I pull out the enricher (choke) I get a
300 rpm increase and smooth running. Looks like it's running too lean.
Now is there some clever person out there who can tell me how to change the
mixture? The Rotax heavy maintenance manual has some reference to the jet
needle saying it controls the fuel consumption under part load. Standard
position is 2. I assume I would have to lift the needle by one ring. Do
you need to strip the carbs to do this? The really bad diagram in the
manual seems to indicate that you only need to take the top off the carb.
Thanks.
Dave

I haven't worked on Rotax engines (yet) but for what it's worth I have
worked on a lot of bikes and older car engines and this kind of surging was
usually (in my experience) a result of a lean part-throttle condition. I'd
be thinking of looking at your jetting for part-throttle cruise and possibly
richening it up some (assuming that your fuel delivery system including
carbs is working properly).
That's my 2 cents...

Frequently Urban Legends like this scoot around the Internet via e-mail.
Don't ever post them on a mail list and in general be skeptical and
check odd sounding stories out on one of the several good Urban Legends
sites like Snopes and MiningCo.com before passing them on.
The sign-on rules for this list request that people not post way off
topic stuff and this is a pretty good example of why.

Dave.
The jet needles control mixture setting (other than at idle where the air
metering jet controls mixture - this is the small screw on the LH side of
the carby).
If the needle hangs lower in the carby (raising the needle retention clip)
the mixture is leaner and if you raise it the mixture is richer.
The needle can be adjusted by just taking the top cover off the carby and
lifting the internal assembly out by the throttle cable. Then you have to
compress the spring with your hand and you can pop the small cable lug out
of the hole in the bottom of the slide. Move the lug across so that it can
be withdrawn through the larger hole and then you end up with the slide,
spring, plastic retainer and needle/clip assembly in your hand.
It sounds complicated but once you take a look at it. It will make sense.
The whole operation takes about 5 mins.

As usual, this is very interesting reading and I make a good note of it.
However, I still have this problem: although I know how to change my needles
(they are now at the lowest position - the richest mixture) on my 582, I don't
know that I should aim for. With the OAT around 0 C, I get the highest EGT
around 4,800 RMP, then again up at max RPM. I understand that engines with
mixture control handle, once at level, lean to the hottest EGT then make it a
tad richer. Say that my cruise RMP is 5,800, when should my mixture be leanest
(highest EGT)?
Just to make sure I got this right: When it is cold, the air is denser and the
needle needs to go up so that more fuel can come to meet the right mixture,
right? It's like a plane with mixture handle where the pilot enrichs it when
going down in denser air.
Again, thanks for the great list with incredible knowledge. I owe you all that
I dare going up in that plane feeling safe.
Cheers,
Michel

Merry Christmas from Target !!
by Dick Forrey of the Vietnam Veterans Association
Recently we asked the local TARGET store to be a proud sponsor of
the Vietnam Veterans Memorial Wall during our spring recognition
event.
We received the following reply from the local TARGET management:
"Veterans do not meet our area of giving. We only donate to the arts,
social action groups, gay &lesbian causes, and education."
So I'm thinking, if the Vietnam Veterans Memorial Wall and
veterans in general do not meet their donation criteria, then
something is really wrong at this TARGET store. We were not asking
for thousands of dollars, not even hundreds, just a small sponsorship
for a memorial remembrance.
As a follow-up, I e-mailed the TARGET U.S. corporate headquarters
and their response was the same. That's their national policy.
Then I looked into the company further. They will not allow the
Marines to collect for 'Toys for Tots' at any of their stores. And
during the recent Iraq deployment, they would not allow families of
employees who were called up for active duty to continue their
insurance coverage while they were on military service. Then as I dig
further, TARGET is a French-owned corporation.
Now, I'm thinking again. If TARGET can not support American
Veterans, then why should I and my family support their stores by
spending our hard earned American dollars and to have their profits
sent to France. Without the American Vets, where would France be
today?
Feel free to pass this along to whomever you want.
Sincerely,
Dick Forrey

You have it right - cold dense air means a leaner mixture so you have to
lift the needles to allow more fuel flow to compensate.
Your EGT's will be a function of fuel mixture and prop pitch on a two stroke
- finer pitch means less load and therefore a leaner mixture and higher
EGT's
On my set up with the in-flight adjustable IVOprop I can fine tune my EGT's
by changing prop pitch. I set my pitch for a climb out at 6500 rpm and just
before I begin to level out I increase the pitch at WOT to reduce RPM to
6100 rpm. Then I just throttle back to 5700 and my cruise speed is around 90
mph. Fuel flow is 19.5 Ltr/hr and my EGT's are at 1050 (OAT is -10 deg C)
During my climb out at WOT my EGT's peak at 1175.
Prior to landing I reduce pitch at WOT in level flight to achieve best take
off pitch at 6500 rpm however sometimes I need to increase the pitch
slightly to keep EGT's under 1200 during extended descents.
It all depends on load and temperature.
Hope this helps

Over the Christmas break I managed to go with a few friends on an ice
fishing trip. A Challenger, Cessna 180 and C-IGVW.
It was only a short flight from home, about 40 Mile but the fishing was
pretty amazing. This same trip takes anglers with snow machines over 7 hours
in some pretty dense country but we took 45 minutes to get there and well
under 30 minutes to return. We had some pretty stiff winds at around 30 mph
but it was silky smooth. Flying in and out of these smaller lakes takes a
little care and preparation but it's a great deal of fun
We ended up catching 16 Splake (Cross between a Speckle and a Lake Trout)
with the biggest being 5lb. In the photos I'm the one with the Furry Baron
from Banff hat.....
I was home by 5.00pm and the fish were in the pan within an hour - all in
all another great Kitfox day/
I have posted some photos on Sportflight under the Flyins section if anyone
is interested.

It's interesting to read about your technique using the IFA IVO prop. I've never
heard the procedures first-hand, but they seem to be appropriate. I'm thinking
about using the same setup up my Model-3. However, I'm not sure if your fuel
flow of 19.5 Ltr/Hr (about 5 G/Hr), is this a 'normal' rate for this engine?
I would think that an IFA prop would improve fuel economy. I don't think
my 582 burns fuel at that rate, but I may be wrong.
I currently use dual in-flight adjustable needles to adjust the EGT

Thank you for this explanation, Gary. Unfortunately I don't have a in-flight
variable pitch prop. However, I can see how denser air affects it. In the
summer I get 6,800 RPM at max throttle but in the winter, only 6,400.
My question is really this: If you care to look at this drawing:
http://home.online.no/~michel/tmp/tmp.gif
and knowing that my needles are in the highest of its four position, should I
be happy or should I change something?
As it is now (in winter) I try to avoid the 4,800 RPM because the EGT gets
quite hot. Exactly how hot is difficult to say because I have not a symmetrical
reading on both cylinders. I know that it is not the cylinder but rather the
sensor because when I switch them, the reading is asymmetrical the other way. I
any case, one is slightly over 1,200 and the other, under 1,200. Playing safe,
I avoid this RPM region.
Thanks in advance for your advice.

If you are only reaching 1200 deg in Winter at 4800 rpm I wouldn't be
particularly concerned. I believe that the sensors read high at lower
temperatures anyway but perhaps Bob Robertson can confirm this

19.5 Ltr/hr is my average fuel burn in Winter (-10 to 15 deg C) in the
summer I get around 17 Ltr/hr.
This calculates to approx 4.3 Imp Galls/Hr which is around the range that
Rotax claim
I measure this straight from my Mizer fuel flow meter.
I would love to add the in-flight adjustable mixture controls then I think
you could really get some serious fuel economy.

I wouldn't worry about the 1200 degree temp. I ran my 582 for 400 hours at
that temp and 5900 cruise and never had a problem. Cylinders were like new
and pistons were clean on decoke. Burns a lot less gas too. I used
Pennzoil Premium Aircooled exclusively.

Dumb question?
I am ready to change oil in my engine.
THe question is how do I get the oil out of the tank?
I can't get to the plug in bottom of tank to remove, so will I have to remove tank
from aircraft to change oil?
Also how often do I need to change oil and filter?
I have 20 odd hours on a new engine.

Hi Folks,
Just downloaded a huge amount of mail!
This is one thing I'll try to answer.
During some time, I've often been talking about the "cold junction"
temperature. Now, what is this cold junction temperature??
Well, this is the temperature at your EGT INSTRUMENT where the EGT wires
is connected! The joint between the EGT cable and the instrument
connection. The instrument connection block is made of a different
materiale than the EGT cable (also reffered as the thermo cable),
therfore we'll have a voltage present over this junction as well, and
this is the cold junction point.
A number of the modern instrument have a built in cold junction
compensation, so the temperature you read is the corrected and true EGT
temperature!
But for our simple system we need to compensate for the "cold junction"
temperature. So, by practical reasons we use cockpit temperature as
equal to "cold junction temperature".
So, now to our more simple system like Westack and alike, without cold
junction compensation.
As the temperature in cockpit change, we now that this cold junction
temperature will give error to be corrected, right.
The first thing to be remembered is the temperature the instrument is
calibrated in, normally this temperature is 70 deg. F. (But check this
out for your system, OK).
The correction is as follows:
True EGT = Reading - (70 - cockpit temp). Here you clearly see that a
cockpit temperature of 70 deg. F give no correction.
So, low temperature (less than 70 deg.F) in the cockpit will subtract
from instrument reading, and higher than 70 deg. F will add to
instrument reading.
OK. Thats all folks.
Hope this clear out..
Cheers
Torgeir.

Leave that plug in and keep it safetied. There is a quick drain you can
install in its place but it is still hard to get to. Buy a huge syringe or
turkey baster. Warm your engine and remove the bottom plug. Drain that oil.
Clip the safety wire on the oil tank and remove the lid. Have plenty of
paper towels handy and go to the grocery store and by some surgical gloves.
Wear the gloves and take the guts out of the tank cleaning them as you go.
Take the syringe or turkey baster and remove the oil from the tank. When the
tank is empty wipe it out. Clean the screen and put the tank back together.
Change your filter and when you put the new one on, put a hose clamp around
it and safety it. You are done. I think we are suppose to change the oil
every 50 hours. I'm not sure about it. I change mine every 25 hours. Jeff

OK, sure you can, but-.
Can you be sure that this error is in the instrument? Most probable,
-and the sensor may be within 5 percent.
The instrument is "nailed" together by this combined nut/nail, so if you
drill out those 4- you'll have access to the internal of the instrument.
However, the only adjustment's you can make, is the two: The zero and
the spring strength.
OK. the zero is obvious (!), and the spring tension is the maximum
reading.
But, before anything SHOULD be done, check the instrument first. Lot's
of people think this is very difficult, but- if you take time- study
this thing -and are sure of what you are doing (!) there is no problem.
This is true for all the work we do on an aircraft!
There is an early service information about the installation of a Rotax
engine instruments giving all the details about values for EGT, water
temp etc. lot's of good info here, -and be sure, this SI is still VERY
good, and this is also true for those using the four strokes!!!
This is the SI 6 UL 87, according to the old "identification" system.
Well, go to page 8, there is two tables, one for Chromel-Alumel
(NiCr-Ni) thermocouples and one for Iron-Constantan (Fe-CuNi)
thermocouples.
The normal standard we are using for Westach etc. is Iron-Constantan, so
use the latter table.
In this table, you'll find A VOLTAGE, yes this is mV-, so you'll need a
mV generator to do this test, however, I'm sure you'll handle this
"small" problem.. :)
If this check verify instrument error, we'll make a correction-, but
this will take place in the next chapter. :)..
Cheers
Torgeir.

I'm new to the 912 series but ,one thing you left out: In the Manual it say's
to fill the new Filter with oil befor installing it. I guess it goes back to
the old filter without a Foot Valve, you'd have to pump about 1/2 a quart of
oil befor it started circulating through the Engine.I did this and very little
comes back out when you're screwing it back on.Do put a Rag on the Floor
though it will make a little Mess.
Thanks David Cecil

Another lister gave me the setup on this list. I don't remember the exact
tubing spec but I believe it was 4130 - 1/2" I.D. and 5/8 O.D. Aircraft
Spruce again.
