I think it is Matt Cochrane, he sold most of his CJ on Ebay, but held back
his panel and avionics, it's a good buy if you need all the gear.
Always Yakin,

Jim,
If I were you, I would call the EAA gouv affair for guidance before I went
too far with this. There must be another way to do this. Some of the
people now on the EAA payroll are exFAA and actually wrote the order used to
certify Warbird. They know this stuff better then anyone else. If my memory
serves me right, I spoke to Earl Lawrence (920 426-6522) when I had a beef
with the FAA regarding my Fouga. This was a few years back, don't really
know if he still work there, but definitely worth a try before it is too
late.
Hope this helps.

A misfiring problem can be caused by many things. First when it occurs, see
if you can isolate the misfire to one of the two mags. Then we can go from
there.

Although seeming like fuel, we have found that these problems are almost always
electrical on the high-tension side.
Very common for an engine to work perfectly for 20-minutes/30-minutes, and then
misfire etc.
In Egon=92s case I suspect would continue to get worse, but would suspect electrical.

--> Yak-List message posted by: "Richard Goode" <richard.goode@russianaeros.com>
Jerry Painter raises a good point about these.=20
Historically we have found that most operators in the US have either been blissfully
ignorant or not terribly interested in Service Bulletins.
Certainly in the UK our CAA are much more aware of these, and, by and large, insist
on full compliance.
There are also a large number of Service Bulletins. We have all of them for Yak-18T/Yak-50/Yak-52
(widely available through Aerostar anyway)/Yak-55.
We also have them for Vedeneyev.
HOWEVER we are talking about many many hundreds of pages in Russian, which is fine
if you operate with Russian engineers as we do. It would be a mammoth task
to translate all Service Bulletins for all aircraft.
In addition, it is fair to note that many are trivial, but many critical!
What do people want to do?

Egon
The exact same thing you describe used to happen to me. The engine would
stumble at prolonged high speed. I'm not sure what the cause was. The
front louvers weren't installed while this was happening. I installed
new louvers along with the new carb and then the problem went away. I
always suspected one of three things...shock cooling, bad carb or
possibly a resonance developing across the carb inlet (kind of like
blowing across the top of a bottle to make a tone).
Just for grins, try closing the scoop and see if it still happens.

Richard is 100% correct. If the miss occurs after 20 to 30 minutes of
flight, based on experience I would suspect a bad coil in one of the mags.

Thats not exactly correct. While XM does have a weather service, you
need a special receiver to subscribe to that info. Your run of the

One of the key factors is manifold pressure which determines cylinder pressure
when the plug fires. If the problem occurs at higher manifold pressure (800mm
is reasonably high) but not at lower MAP, look for a plug misfiring or a wire
breaking down. The higher the cylinder pressure, the higher the voltage needed
to fire the plug and the more likely it is that the high voltage will take a
different path than the one through the gap on the plug.
BTW, the admonition to try it on different mags will help eliminate half the
plugs and wiring in your troubleshooting.
Generally speaking, if the problem is carburation it will be a more or less
steady-state problem rather the a momentary transient one.

If I were you and had the capability, I would offer it as a subscription
service. People could pay for the information. I suspect that shops
specializing in the CJ6A and Yak variants would subscribe.
Alternatively something like the RPA could allocate funds to do this. (Now
there would be a truly useful service.)

Geeze I love this list! Every one has a idea and they are all good ideas to
boot, but I guess that's why were here...............but in light of the
past postings, I am ashamed of all of you, not one of you thought to suggest
the cure all properties of MMO!! ;O)
Here is my shot at it. Since he noted a airspeed faster than cruise, we
have to assume that he is pointed down hill, no offense intended guys, but
that's the only way you can herd a 52 that fast. Since it is rather hot
there this time of year he might be getting a bit of condensation if he is
not keeping his tanks full and just maybe in the nose down position he is
freeing up that bit of water that would normally not be a problem in level
flight. Just one more idea, but I personally am leaning towards
recommending MMO!
Always Yakin,
Doug Sapp

--> Yak-List message posted by: cjpilot710@aol.com
RPA guys, John Stephenson, Walt Orth.
I need 4 pilots for the Fort Pierce (FPR) airshow. May 20-21-22.
So far I have Craig Payne and Bill Mills on the list. Two of the other guys
had to drop out and I need two (2) more. (Jim Plumlee are you still
interested?)
Fuel, rooms, and local transportation provided. Pilots must have FAST card,
commercial and current 2nd class physicals.
The group will play the part of German a/c in the show, and will be "shot
down" by a P-51. The airshow people will put vinyl German insignias on the
airplanes for the show. These will not damage your paint job. You may do media
rides at your discretion and at their cost.
Because of my needing to fly the B-24 for the Collings Foundation on that
date, I'll not be able to lead the group and former F-18 lead, Bill Mills, will
take my place.
I need to get this firmed out for FPR folks very soon.
Need help. First come, first served. Contact me off list.

Thankyou everyone who replied to my post. This list is a terrific resource! Just
to clarify the symptoms. The engie will run dead smooth all day long in cruise
or climb. The symptom only occurs at high speed nose down. With a nose down
attitude and reduced power eg final approach...there is no problem. The first
time this occured the misfire lasted for several seconds and ceased as I pulled
the nose up and reduced speed. ( really got my interest! ) The most recent
event lasted only 1 second. Once again thankyou all. I will do some more trouble
shooting and report back.
Cheers from Down Under.

Everyone seems to think that this one is electrical. Normally, I would
agree. Most of the M-14's I have worked on that have had "the hard to find
miss" have indeed in most cases turned out to be electrical. Wires, plugs,
Mags, coils... SOMETHING electrical.
What bothers me here is the fact that this aircraft only seems to screw up
going downhill and then only at a very high speed with power on. On every
"the engine is missing" gripe that I have ever seen, it usually is worse
when heading UPHILL.... typically something like straight up, right before
you tail slide, or hammer it.
That said, I am going to go out on a limb here and throw my 2 cents in and
say... I think it is fuel related. I suspect I may have to eat these words
by the way, but I'll take the chance anyway.
So.... after you have tried all the other suggestions, and only if they
fail.......
My guess is that there is indeed something that changes when you are coming
downhill fast and that is the barostat that controls fuel mixture with
altitude. It that thing sticks just a little, the engine would go lean and
would miss. All it would have to do would be to stick just a tiny bit. It
would also explain the changes in the TIME DURATION of the miss. Dare I
suggest MMO and a LOT of it for one tank of fuel??? (He says running for
cover) Anyway... suggest getting a good diagram of the carb and checking to
make absolutely sure there is no blockage to the air ports at all, and to
check the setting of the barostat ... which is not all that hard to do.
There is a chart that shows length of the rod, you just read off the value
with your local barometric setting and measure. If the aircraft ALWAYS does
it on every flight by the way... also would suggest going a few clicks rich
(as in 1 or 2) on the mixture and see if it helps.

Thankyou everyone who replied to my post. This list is a terrific resource!
Just to clarify the symptoms. The engie will run dead smooth all day long in
cruise or climb. The symptom only occurs at high speed nose down. With a
nose down attitude and reduced power eg final approach...there is no
problem. The first time this occured the misfire lasted for several seconds
and ceased as I pulled the nose up and reduced speed. ( really got my
interest! ) The most recent event lasted only 1 second. Once again thankyou
all. I will do some more trouble shooting and report back.
Cheers from Down Under.

Good point Mark. I wonder if he has cleaned the fine fuel screen? I'd
check it anyway.
