--> Europa-List message posted by: "Stephan Cassel" <cassel@sensewave.com>
Hi Mike
I have been told by the factory (Nev and Andy) there
is only one way out: fill in order to blend it out. I took a look
on a Cessna 172, just to see how the flap and the aileron lined up:
it looked very bad. The tip-moulding, aileron and flap did not
line up at all. After the "172-inspection" I can live with small
misalignment (big misalignment blended out).
My guess is that the misalignment problem will be mentioned in the
Europa Newsletter one day.

--> Europa-List message posted by: DuaneFamly@aol.com
Good day All,
This is a follow up of my previous question. Thanks to those that steered me
towards the wingtips being built to the wrong dimension. I have just
finished
mounting the flap and aileron on my port wing. I also took the time to
reinstall the flap and aileron onto my starboard wing. The trailing edges of
both the
flap and aileron, on both port and starboard wings, line up just fine. But
the wingtip makes a big misalignment towards the outer end of the aileron.
Has anyone fought this problem already? What steps did you take to resolve
it? What did the factory have to say? I hope that I don't have to fill in
then
feather out both ailerons!

--> Europa-List message posted by: "Stephan Cassel" <cassel@sensewave.com>
Hi All,
I have read number of messages about Rotax problem round 400 hrs mark or
less.
I not yet decided what engine I will install. Must likely a Rotax 912S.
But I am getting worried about these messages.
I used to have an old Cherokee with an old Lycomming 320, 1400 hrs
Never any problem. I felt very safe flying 30 years old plane.
Question:
Is Rotax a safe Engine? Is it good for 1200-1400 hrs?
I hope so.

William,
Check your CHT temps. If they are too low, the engine can fowl, even on
unleaded fuel. I had exactly the same problem, however when I got the
engine to run a little hotter, it went away. The roughness didn't show up
until the engine had about 400 hrs.
Good Luck!

Hi All,
Has anyone experienced a similar problem and can anyone help with
suggestions please?
On recent flights I have experienced some irregular misfiring when
descending with about quarter throttle and also the occasional hiccup in
cruise, but on my last flight the engine was running so roughly in the
cruise I aborted the flight and nursed it back home.
I carried out some tests on the way back. It ran very smoothly on full
throttle, it ran very smoothly on closed throttle, but in between it ran
very roughly. I checked the ignition when running roughly, but there was no
change on either mag. I tried coarsening and fining the prop to see if it
was rpm related, but it wasn't. I changed to reserve tank, but no change.
The carbs are well balanced at tickover and the engine runs smoothly right
down to 1500 rpm. The fuel filters are clean. I can only assume that the
problem is related to carburation, but find it difficult to believe that one
can have a partial blockage, or too much fuel with a needle jet in its mid
range only. As tickover is smooth and roughness stops in flight when
descending with closed throttle, I can only assume that the slow running
mixture adjustment and associated jet are OK. Are there any other jets
apart from the main needle and slow running jet to consider? Although I
never have a problem with !
starting, can a problem with the starting carb affect the mid range running
only? Can a faulty float valve affect mid range only? My engine has done
about 480 hrs, should I be considering renewing any of the carb parts as a
precaution / planned maintenance etc? I have had a brief chat with Conrad,
but he was unable to put his finger on the problem, so presumably my
symptoms are unusual. He suggested I should check the needles for wear and
the carb rubber mounts / sleeves for splits, which I will.
Many thanks for any help,
Regards,
William

Thanks Stephan. I guess I'll have to do some "artistic filling" in order to
cut down on the drag that the misalignment would cause. What do you plan to use
for the filler? I have the Q-Cell stuff, but am not too sure on how to
approach it. I'll have to put some thought in to it.
Good luck.

Many thanks, John,
I try to keep my coolant temp up to about 90deg.C by partial blanking of the
rads. However, I have found a small slither of silicone in one of the
needle jets, which might have been the cause.
Best wishes,
William

Hi Ira,
Tick-over is another term used for idle. I have found a small slither of
silicone in one of the needle jets, so I hope that was the cause.
Best wishes, William

Hi Dave,
Thanks for your suggestion. All seems to be OK with the pipes and hoses,
but I found a small slither of silicone in one of the needle jets, which I
hope will solve the problem.
Best wishes,
William

Hi Ferg,
Many thanks for the suggestion. I have checked for all possibilities of
leaking air and have found no evidence. I have found, however, a small
slither of silicone in one of the needle jets, that I hope will solve the
problem.
Best wishes,
William

Hi All,
Just to let you know I received 12 replies to my request for help, most off forum.
The suggestions have been very useful and I have been checking as much as
possible. Most suggestions I found to be OK on my engine, but I found a small
slither of silicone in one of the needle jets, which I hope was the cause.
I will report my findings when I get the chance to test fly and also list the
main suggestions for others.
This highlights one of the important benefits of the Europa Club and this forum.
A problem shared and all that.
Many thanks and best wishes to you all,
William
