If it have that system (I am not sure) there is one or more extra
holes close to the closed throttle valve, clean this and or the idle
jet, and or adjust the idle mixture, because the idle system is working
about one third up in the register.

Off-idle circuit
As the throttle is opened up slightly from the fully closed position,
the throttle plate uncovers additional fuel delivery holes behind the
throttle plate where there is a low pressure area created by the
throttle plate blocking air flow; these allow more fuel to flow as well
as compensating for the reduced vacuum that occurs when the throttle is
opened, thus smoothing the transition to metering fuel flow through the
regular open throttle circuit.

Ok, So far I cleaned out the top diafram area with carb cleaner, and
the needle had a slight dark ring of residue on it on both pins.
Diaphrams are fine, and back in place
Inlet tubes look fine,
Carb sockets have about 20 hours on them, and are clamped correctly,
One thing I noticed when taking off the top cover of the carbs there
is a dark silver / oil looking residue on the two parts that hold the
big spring in place. I did not know if it is oil for the spring or just
the aluminum rubbing off from the spring. I left it as is for now. Test
ran it and the same issues are happenning.
I ran out of light so I will try the plugs, and the teflon seat and
valves for wear as per the maitenance book.
I know of people that change the jets 2 X per year depending on
temps, but since I built it I have not had to change them at all. The
egts have been great and only fluctuate very little all year round
90deg- 20 deg F.
Where is the middle range system located? Is that up behind the
float valves?
I hope to get over there Thursday sometime.
Thanks

Hi List,
I have a 912 UL with 145 tthours. It had a rough spot at about
3000-3200 rpms on the ground or in the air.
I have checked and regapped the plugs to .028,
cleaned out the bowls on the carbs,
cleaned off the neddle and dome area, sanded the ground wire
lugs for the coils to get a good ground.
Checked the carb Ballance -its ok.
It all has not helped at all, even makes the rough ness worse
some times. Going from 2k rpms- 3k rpms it is almost like it is bogging
down, and you have to sort of pump the throttle to get the rpms past the
3-3.2 k mark.
Doing the mag check it is very rough on each side also, and I am
using gas with the 10 % methanol( exact amount unknown )
My qquestion is any ideas on the cause, there was no visible
dirt or matter in the bowls either?????
I am going to try and put in new plugs and then try some AV gas
instead.
Let me know what you think
Thanks

Got the figures. thanks
They are well ahead of what I'm getting around the same weight on Aerocet
straight floats. I actually haven't done any measurements on take off
distance but the times are around 8 to 10 seconds.
My climb out is initially around 1000fpm @ 6800rpm.
I cruise at around 6000 to 6200 rpm and the ASI reads around 75 mph GPS
readings average out to around 100mph.
I also changed from a GSC 68" prop to an Ivo in flight adjustable. I found
the performance to be improved but the biggest change is the Ivo is lot
smoother. In fine pitch ( take off ) the Ivo doesn't ingest as much water
as the GSC there fore doesn't have the same problems with water pitting.
One thing that boosted my overall performance was the installation of a Tiny
Tach. The original Kitfox tach was so far out to lunch I doubt it will ever
come back. I'm considering removing it.

Unless there's an option to do just that here's a workaround. In your
email program create a filter that deletes all kitfox messages from
kitfox-list@matronics.com and then just use the web based forum as you

Frankly, and this is just my opinion, obvoiusly, I think this is exactly the
problem that the list has developed. The forum set-up resembles all the
open topic chat rooms out there and it has attracted all the nonsensical
chit chat and multiple posts you see in the chat room environment and they
are all posted to the Kitfox list.
I think a quick review of the timing of when this phenomenon started - it
would be about the time this option opened up. For about 14 years the
Kitfox list opereated pretty much as it was intended, then whamo.
As before, just an opinion.

To Matt and the Kitfox List.
Too just add a little bit to this. One of the downsides of using the forum
feature is that the message that is being replied to isn't automatically
appended to the outgoing message. Therefore, often when we receive a post
here on the List there's a message, but it often makes no sense because we
can't tell what is being replied to. The subject line gives a clue, but
often that is many posts old. I'll pass this on to Matt.

But with the forum format, attaching the old message is unnecesary and redundant
because the web site keeps all the messages neetly organized. The problems arise
because we're trying to do this dual personality web/email aproach and what
works for one doesn't always work for the other. I believe that it would be
best to just pick one.

| Subject: | Left turning tendency |
My Model IV-1200 speedster has a slight tendency to turn to the left which requires
some right stick pressure. If pressure is held the ball stays right in the
middle with feet off the pedals. I tried turning the left rear strut in 1, 2,
and then 3 turns with limited results. I then set the left one at 2 turns and
turned the right out 2 turns. The result was that there was still the tendancy
to turn left but I also had to add a little right rudder to keep the ball in
line. What do you suggest, change the adjustment of the flapperons? John May

should be tested, at altitude, as they are accomplished so you won't run

My Model IV-1200 speedster has a slight tendency to turn to the left
which
requires some right stick pressure. If pressure is held the ball stays
right
in the middle with feet off the pedals. I tried turning the left rear
strut
in 1, 2, and then 3 turns with limited results. I then set the left one
at 2
turns and turned the right out 2 turns. The result was that there was
still
the tendancy to turn left but I also had to add a little right rudder to
keep the ball in line. What do you suggest, change the adjustment of the
flapperons? John May

I expect the switch you have has a set of normally open contacts (NO) and a
set of normally closed (NC) contacts. you will use the NO set.
Past that follow the documentation that came with your intercom.

The changes don't seem to seem to have made any change in stall recovery.

I just checked the Sigtronics site and realized the SPO intercom has a
transmit switch for both the pilot and the co-pilot. Usually the
co-pilot
won't have a PTT switch unless the plane is used for training purposes.
under normal circumstances there is no need for a passenger to operate
the
radio. the Intercom for both the pilot and passenger is operated by
VOX.
Assuming that you are not training then install the PPT switch to your
stick
with the wires soldered to the NO contacts. route your PTT wire to the
flight location of your intercom box. Solder a 1/4" jack to the other
end
of the PTT wire and plug that into the Xmit hole of the headset side you
will be using. When you push the button only the headset that you have
the
ptt switch attached to will be heard over the air. Pushing the ptt
should
also cut out anything that the passenger is saying on intercom. RX (
Received transmissions) from the com radio should also cut out anything
that
is being said by any one on the intercom.
Assuming that I was wrong in the first assumption ( that happens ), wire
the
passenger side ptt the same as the pilot side and put it's jack into the
passenger side XMIT receptacle. This will allow you, if instructing to
operate the com radio. BTW when the passenger button is pressed the
pilot
will not be heard on the air unless the pilot pushes his ptt button at
which
time the passenger should be cut off.
Operation of the intercom should not require the use of any PTT buttons.
those buttons are only to operate the com transmitter.
Wiring the intercom to your radio..... To an extent depends on the
radio
itself.... Panel mount or portable etc. etc..
Generally the two jacks that are attached to the two wires coming from
the
intercom will plug into the com's headset and mic receptacles. There
should
be a smaller wire that will plug into your radios PTT input. Portables
usually have, I think it's a 1/8" jack receptacle.
All this should be covered in the documentation that should have come
with
the intercom. As in most things best RTFM.

John,
How dependent is the stick pressure on speed? If highly dependent,
then you probably have a rigging problem. If not very dependent then you
probably have a mass / CG problem. I might try some throttle-off dives,
slowly pitching in and then out to see how the stick force and deflection
angle vary. Try to measure the stick angle by attaching a piece of masking
tape to the bottom of the instrument panel and taping a pencil or other
pointer to the top of the stick. Obviously you'll want to do it in still air.

Hi John=0A=0APut the wing rig back to where you only had to hold a little s
tick pressure. Then level the wings by adding a trim tab to the flaperon.
If you want to test this solution before adding a trim tab just put a litt

s will have the same effect as adding a trim tab It acts by lifting the tr

| Subject: | Buffed down tyres |
Rex,
I have an extra set of tires that are the smooth buffed atv tires. I
was planing
on using them on my classic 4 when my lawn tractor tires wear out. What
was
"shocking" about yours?
Tom Jones
Ellensburg, WA
Tom,
the buffed down tyres were only two ply and they only had to
see a grass field and they went flat. My Lawn tractor tyres are 4 ply.
I couldn't find tubes for the buffed down tyres and that didn't help. I
have 8" steel rims with brake disk lugs welded on the back. This causes
slight distortion on the inside and leads to poor sealing without tubes.
The buffed down tyres were squirmy at 9-10 lb pressure at times but too
tight at higher pressure. I think my slightly smaller Lawn tyres handle
excellent at 18 PSI. I used green slime sealant in the buffed down tyres
only to find it started attacking the rims. All in all I don't want to
see them again. I couldn't put them in the bin fast enough.
Rex.

The plane was hanging on the left wing!
You want the left aileron down and right one up.
If the rigging didn't have any effect it might be so that the flapperons
isn't symmetric, just a small deflection on the trailing edge of the
aileron7flaperon can have this effect.

John, I had the same problem and I did what Jim says. It's all fine and
dandy now.

I will do some testing but off hand I would say stick pressure increases with speed.
Assuming it is a rigging problem where do you suggest I start.
