The original kit Avid included one inch rather high density sound deadening
foam which was to be glued to the back of the cockpit side of the fire
wall. I did not think it made much difference until I flew one without it.
The un dampened fire wall set up its own frequency and became another sound
generator.

Just ran across a document out on the Rotech website
pertaining to the 912/914 and ethanol.
http://www.rtx-av-engines.ca/PDF/techinfofuel.pdf
There's a statement that Rotax recommends use of 5%
max ethanol. Then Rotec adds a rather pragmatic
statement basically saying that the Rotax
recommendation isn't practical and 10% is what's
widely available.

Here is how: Put your fingers in a space/time wormhole after setting
your photon accelerator to ... about, 42.
Your fingers should come back on the other side, as they were about ten
years ago.
Warning: Do not abuse the wormhole or your fingers will come back as
baby fingers and it makes polytak cementing very, very difficult!
... And now, I have to run before the nurse tries to give me my
medicine!

Good Morning, new to the forum and find it very interesting.
Hope someone could help with my problem.
Just got the Kitfox flying after a three month stay in hanger due to winter and
soft field. Have put about 4 hours on it in the last couple of weeks
We have a small engine miss if we cruise at 4600 to 4800 rpm. If carb heat is pulled
the engine smooths out perfectly. If 5000 rpm is used the engine is fine.
I assumed it was a mixture problem or a plug problem as carb heat will richen the
mixture so I pulled the plugs, I found the front clyinder plugs on the black
colour side so I really do not want to richen the mixture any more, the back
plugs were perfect colour. Gap was also perfect at 27.6 th.
We are running a 912 u engine with DCPR7E plugs.
Would appreciate any help or suggestions.
Thanks
Marty Marks

Marty,
If your carbs are jetted identically, then the difference is due to an air
leak in the rear cylinder. Basically, your mixture is set too rich, and the
leak is leaning out the rear cylinder to the correct mixture.
Check and double check the intake tracks post-carb. Re-torque the intake
bolts, even get new gaskets.
Bradley

Yes sticky fingers,
Now that we have alcohol to talk about, I think I'll
drop the subject, but it was fun for an off topic
subject to fill time and space with - time and space.

To the List: Thanks for all of your endurance for off

Clem,
You actually read all the way to the end!
Michels nurse is done with his meds and is heading in
my direction. I'll send her your way when she is done
here. ;-)
After that I'll be unconscious on this subject. I am
down to the last of my 2 cents worth of credibility as
it is.

There are more such announcements:
Light (energy) traveling faster thru an "opaque"
object than the same distance around it?
A magnetic field that creates a shadow blocking
gravity? We already have the AirBus. Don't need any
more means of lift that totally depend upon
electronics to work.

Gents,
I have the same situation with dark front plugs and
good looking rear. Both sides. I don't think that's
due to an air leak. Always been that way.

were dealing with a 912 here, correct? are the plugs on both front carburators
sooty?
The soot test can be a problem. The plugs can soot up with longish taxi if the
idle mixture is too rich...etc.
Disregarding the soot on the plugs, it sounds like the main jet is correct but
that the circlip on the needle might be lowered allowing a richer mixture in the
mid range.
I really benefited from a bing manual from Bing International 1-800-309-2464.

The soot test can be a problem. The plugs can soot up with longish taxi if the
idle mixture is too rich...etc.
Disregarding the soot on the plugs, it sounds like the main jet is correct but
that the circlip on the needle might be lowered allowing a richer mixture in the
mid range.
I really benefited from a bing manual from Bing International 1-800-309-2464.

Marty,
If your carbs are jetted identically, then the difference is due to an air
leak in the rear cylinder. Basically, your mixture is set too rich, and the
leak is leaning out the rear cylinder to the correct mixture.
Check and double check the intake tracks post-carb. Re-torque the intake
bolts, even get new gaskets.

Good Morning, new to the forum and find it very interesting.
Hope someone could help with my problem.
Just got the Kitfox flying after a three month stay in hanger due to winter
and soft field. Have put about 4 hours on it in the last couple of weeks
We have a small engine miss if we cruise at 4600 to 4800 rpm. If carb heat
is pulled the engine smooths out perfectly. If 5000 rpm is used the engine
is fine.
I assumed it was a mixture problem or a plug problem as carb heat will
richen the mixture so I pulled the plugs, I found the front clyinder plugs
on the black colour side so I really do not want to richen the mixture any
more, the back plugs were perfect colour. Gap was also perfect at 27.6 th.
We are running a 912 u engine with DCPR7E plugs.
Would
appreciate any help or suggestions.
Thanks

If you stand and stare at your engine which I have done many times ( not in amazement
but in frustration) you can see the reason there is a different color on
the front and rear plugs. The intake on the rear does an immediate 90 degree
bend with a very short distance. The front intake is a longer distance kind of
straight. Hence the leaner on the rear and richer on the front. Also, Pierre
Landry told me that if you remember him. He spent 6 months of the year in Austria
at the Rotax factory and 6 months in Canada working for Rotax there. Jeff

Thanks John, yes 912 and the front plugs are sooty.
We will check the circlip as well. Thanks.

I agree Jeff but would this cause the miss at 4600 to 4700 RPM remembering
that the carb heat will eliminate it?
If the plugs are black in the front I sure do not want to richen the
mixture to simulate the carb heat, I figure it will worsen the problem but
really do not know.

All,
I started the Rotax 582 for the first time today, and everything
was fine but the tachometer and the charging. I'd like some help
de-bugging, if I may.
Configuration: Rotax 582 grey head w/ 3-phase regulator wired per Z-17. GRT
EIS tach wire connected to yellow alternator output wire.
First start: Tachometer reads 0. No variation in voltage switching
alternator in or out, regardless of RPM. Voltage about 12.9V.
Disconnect regulator from alternator. Measure ACV across alternator and get
Rotax spec values. (~14 - 55 VAC depending on RPM.)
Re-connect regulator input wires and disconnect output wire and measure
voltage between it and ground: ~5 VDC invariant with RPM. Note that the EIS
RPM is now working.
Re-connect the output wire and clip DC volt meter between the regulator
output and ground: ~ 14.1 VDC at idle, decreasing to about 5 VDC at higher
RPM. EIS RPM is 0 again.
Basically I'm clueless as to how to diagnose whether the charging
system is working beyond the alternator output. Any help would be
appreciated. I think whatever's influencing the charging is probably
inhibiting the EIS RPM input, as well.
Thanks,
Guy Buchanan

--> Kitfox-List message posted by: Malcolmbru@aol.com
We=E2=80=99ve been Duped, =E2=80=9CAmphibians Need Retracts=E2=80=9D
The committees worked vary hard to get Sport Pilot and Light-Sport Aircraft
right the first time. As with all complex rule changes, we missed the mark.
But, it is not our fault! Really!
There were many discussions on retracts for amphibious aircraft. We knew we
had to have something that worked. The answer seemed easy. Call them=20=E2=80=9C
repositionable gear=E2=80=9D. After all, that is what happens. These gear are
not
changed just after takeoff or just before landing. They are never changed=20just
for performance improvement. They are changed to get to a new mode of
interface with the earth, both wet and dry.
How can you say the Buccaneer pilot who leans out and hangs his gear up on=20a
hook, stretching the bungee cord that keeps it attached to the socket, is
doing a complex job?
We thought we had our FAA counterparts convinced. I briefed hundreds of
people, =E2=80=9Cnot to worry=E2=80=9D FAA understands and we will get it done.
While in
reality, =E2=80=9CWe=E2=80=99ve been duped!=E2=80=9D
What happened? How could this be? It was a simple change just one to thing
to understanding. For us =E2=80=9Crepositionable means simple
non-performance-enhancing gear moved in-flight.=E2=80=9D
But for =E2=80=9Csomeone=E2=80=9D in FAA, repositionable means, =E2=80=9Ccannot
change in flight=E2=80=9D.
See the Federal Register, 69 FR 44801, it reads,=E2=80=9D Repositionable=20landing
gear remains fixed in its position from takeoff through landing=E2=80=9D. =20That
is
all it took!
Everyone, including the government, knows that an amphibian is safer to
emergency land gear up. Everyone, including the government, knows that=20the
reason to carry gear is to use it. A wheeled carriage will achieve the same
thing as government=E2=80=99s definition of =E2=80=9Crepositionable=E2=80=9D.
Everyone, including the
government, knows that a Sport Pilot can handle distractions such as radios,
flaps, fuel valves and GPS, but somehow moving a lever is too much.
But, wait, there is hope. FAA personnel have promised that this is being
addressed with all haste. Read, =E2=80=9Cat the speed of government.=E2=80=9D
That means a
least a year, maybe more. Meanwhile, manufacturers are dying while they
wait to sell their product. Worst yet, pilots go untrained because we cannot
bring in legitimate ELSA amphibian trainers. Owners cannot fly legitimate
Amateur Built amphibians because their training as Private pilots cannot be
applied to their Sport Pilot privileges.
How do we fix this NOW, before it is too late? The answer is a bridge
exemption that will let us function now and the rule can catch up at the=20=E2=80=9Cspeed
government=E2=80=9D. Mermaid was the first to apply. On April 4th they were granted
the exemption. FAA personnel have said =E2=80=9Ceveryone should file individually
for the exemption=E2=80=9D. Right! Three hundred new exemptions moving=20through
the
Federal Register at the =E2=80=9CSpeed of government=E2=80=9D, not my idea of
a good plan
If that is what they want, OK. We can follow direction. ASC and SAFE=20=C2=AE
have already filed over 24 exemption requests in support of manufacturers and
individuals.
But, there is an easier answer. ASC has filed two =E2=80=9Ccommunity exemption
requests=E2=80=9D that will be administered by ASC for =E2=80=9Cfree=E2=80=9D.
One will allow
manufacturers and owners to certify Special Light-Sport Aircraft (SLSA) and Operating
Fleet Experimental Light-Sport Aircraft (ELSA) which are amphibious. The
other will allow Amateur Built Experimental Aircraft (AB) which are amphibians
to be used by pilots operating under the limitations of Sport Pilot
privileges.
You can help. Please comment in support of the exemption requests. It is=20
easy. Just got to _http://dms.dot.gov_ (http://dms.dot.gov/) . First
download and read the lead docket letters. Then go back and submit a supporting
comment to the dockets:
Community SLSA/ELSA with retracts Docket 24241
Community AB amphibians a LSA Docket 24468
Other individual dockets 24129, 24434-36, 24469-82
The community needs your help. The FAA needs to move on these =E2=80=9Cbridge=E2=80=9D
exemptions quickly. Tell them that. Write and help.

Seems no one was interested ion the like new IHI turbo for the Turbo
Subaru, but I also have a new set of forged .020 over pistons for the
EA-81 engine. They are complete with new rings, piston pins and keepers.
I had the crowns ceramic coated by Swain industries and the skirts
coated with anti-friction material. These are top of the line and ready
to install. Let me know off list if interested. Once these items go on
EBay the world will be looking.
Few other items going as well: (more later)
Yaesu VXA-200 with programming software and cable, extra NMhi battery,
has pressure sensor and density altitude display, 5 watts, 150 ch
memory, VOR NAV, NOAA weather, temperature, doesn't get any better.
CO guardian carbon monoxide detector, plugs in to lighter socket,
visual and audible alert.
Two E.I. digital EGT gages
CAP 140 electric adjustable prop hub, needs new blades, comes with
reusable hubs to be put on new blades.
Composite flat COM/NAV antenna by advance Aircraft electronics model
VHF5-1
Thanks
