I had a similar problem that in fact forced me down, it was an air leak from a
crack in the primer bulb.

My engine is not running quite "right".
It's a Cuyuna ULII-02 on my UltraStar. Always ran great (though at the end
of last season I had to replace the rear crankshaft seal which was leaking,
and it again ran great after that). Last week, after flying to another
airport and filling up there (with avgas), on the flight home it started
behaving like it was running rich, wouldn't hold cruise rpm without sagging
so I was constantly jockeying the throttle. Today, I couldn't get the
proper 6500 rpm static, more like 6100, and after some extended low
throttle running it wouldn't accelerate to full throttle, just wanted to
quit. That's happened before if set to rich and dropping the needle one
notch fixed that, but the WOT rpm is still low. EGT is also lower than it
should be I dropped a jet size (one size smaller than it should be for the
current air temperature) and it's a _bit_ better but still not right. Fuel
consumption also seems to be up but I haven't quantified it. Avgas does
tend to run a bit richer than ethanol contaminated autogas but now the tank
is half avgas and half autogas and it's still running crappy.
I tried running without the air filter, no change. Spark plugs look OK. I
might suspect the float level but how would that change? Float needle was
replaced last year with a viton needle, shouldn't be bad yet.
Any ideas?

But an air leak would cause a lean condition... all my symptoms point to

I doubt it... the trouble seemed to start after filling up with avgas
(which has pretty good quality control and no ethanol) at Simsbury.

Folks:
My Cuyuna ULII02 was very sensitive to over-rich condition.
I installed a CPS in-flight adjustable main jet on the Mikuni carb. Just a
tad rich over optimum power settings, the Cuyuna would shut down, just like
hitting the kill switch. Never had an engine that was so sensitive to a
slightly over-rich condition.
The Cuyuna, mounted on my 1984 Ultrastar, consumed a lot of 100LL. It ran
the same on 100LL as it did on 93 octane mogas without alcohol. My 447
operated the same, as well as the 80 and 100 hp Rotax 912. Only noticeable
difference between 100LL and mogas on the two strokes was slightly lower
EGT. Don't know about the 4 strokes, I don't run an EGT gauge.

A couple thoughts - does it have a metal float or a composite one? I have seen
composite floats set lower than they should and cause excessive richness.
Do you have a Mikuni and does it have an enrichner circuit like the Bing? Is it
possible for the seat of the device to have a leak, and let fuel seep around
it?
If you have an enrichner, how is it actuated? I had a friend with a J-3 kitten
and his panel mounted lever got a glitch and would not let the enrichner seat
properly as the problem made the cable a bit too short.
And probably none of this is pertinent, but here's hoping.

Boyd,
Your suggestion is exactly what I was thinking, and also what I saw my
instructor experience (crap in the fuel system
on my his QS II ).
Dana, if your engine ran fine at some previous point, I would suggest
NOT changing needle
settings. You don't fix an ailing engine by readjusting it to work with
what is screwing it up. You analyze what
the problem is BEFORE you make any changes, otherwise you never truly
know if you fixed the problem
properly.
If an engine is generally running good, and then starts running lousy,
you look for the likely
causes first. Start out by scrubbing your entire fuel system to
spotless condition. Then, verify
all the components of your electrical system (plugs, wires, connections,
etc.) Next, check compression,
followed by a timing check.
If the problem still persists after verifying that all of the above
are perfect, consider pulling the carb,
and checking to see if the float has developed a leak. I had this
happen on my Cessna Marvel-Shebler
carburetor. The way to check for leaks in a brass float is; you get two
glasses of water. Ice cold and
microwave hot. Hold the float underwater in the cold water for several
seconds. If there is a leak, the
shrinking air in the float will suck in a little water. Then, take your
float out of the cold, and hold it under the
hot water. The rapidly expanding air will literally blast out that
sucked-in water, creating a dirty stream of
clearly obvious filth, along with lots of bubbles.
If the float is still in excellent shape, the dips in the cold and
them hot won't make any difference.
Consider an air leak by spraying some carb cleaner at the joint and
mounting places of the carb. Make
sure not to get close to the air inlet. If the engine accelerates from
the carb cleaner, you have an intake
leak.
Just some thoughts.........

Richard Pike
Richard P/Folks:
That is a good point. Had forgotten about the leaking enricher seat.
Cannot remember if the Mikuni uses similar system as the Bing. Those seats
get old, hard, and leak with age. When they do, they present an over-rich
condition.
The ULII02 has CDI ign, so doubt Dana has a timing problem.
Malfunctioning float/needle valve?
Like I mentioned earlier, the ULII02 doesn't like an over-rich condition and
will shut down in a second.

Jeremy,
I think the lightest-weight non-certified polyester fabric that
Aircraft Spruce sells might be
a better choice the the peel-ply. The peel-ply has sort of a coating on
it, which is why it peels
off fiberglass resin so well. IIRC, ACS has 1.7 oz stuff that would
work fine, or maybe the 2.7 oz.
Since we are talking display model ONLY, I think if it were me, I'd
try a hot glue gun and an iron.
If the heat of the hot glue makes it difficult to work with, then the
next stuff I'd try is that yellow
Carpenter's Glue that they sell at all the lumber stores. It dries
pretty quickly.
Lastly, the fact is, the Poly Tac cement would probably work very
well, too. So would the clear
PVC glue, which is obviously a very close chemical formula to the Poly
Tac. Since a small can
is only $3, give the PVC glue a try.

NTSB Report:
On March 24, 2012, about 1015 eastern daylight time, an experimental amateur-built
New Kolb Aircraft Company Mark III Classic, N528DJ, was substantially damaged
when it impacted trees while approaching DeLand Municipal Airport (DED), DeLand,
Florida. The certificated private pilot and the passenger were not injured.
The local personal flight was conducted under the provisions of 14 Code of
Federal Regulations Part 91.
According to preliminary information provided by the Federal Aviation Administration
(FAA), the airplane was on final approach to runway 23 when the engine lost
power. The pilot deployed the airplane's parachute, and the airplane settled
into the trees.

The question is what was he doing so low in FINAL APPROACH that he couldn't
make the runway?

I imagine he was wishing he had bought a Rotax 912 instead of a Jabiru.

You & I think alike. I always want to be where I can land safely when/if
the engine quits. Lots of pilots simply drag it in with power, on final,
and sometimes get in trouble. I suspect that's what killed Norm
Labhart.
Why NOT fly defensively?

Kolbers:
Yesterday installed new NGK DCPR8E spark plugs, new carb boots, and my newly
repaired and modified Titan exhaust system.
Today I got an hour's flight time, first flight since I landed on my return
from Lakeland two months ago. Neither the MKIII or I had forgotten how to
fly.
All went well. Had a great flight and refresher on what a great little
airplane the 20 year old MKIII is.
After landing at Gantt International Airport, I let the engine idle, got out
to check the exhaust and other stuff on the airplane. Noticed something
dripping from the fuel pump on the 912ULS. Shut down the engine and
discovered the fuel pump is leaking and will have to be replaced. Glad I
discovered the leak when I did. Strictly by fate.
Much rather find it now than half way across the country next month.

Float level, either submerged float or debris on / bad needle sounds
likely, but I shut the fuel valve off while the engine was running,
thinking if a high level in the bowl was the problem it would run better as
the level dropped before it quit. There was no change. I changed the
jetting not so much as a fix but as an experiment. The floats are plastic,
not brass, so that's unlikely anyway. An air leak is also unlikely as all
the symptoms point to rich running, not lean.
Richard suggested the enrichener (yes, the Mikuni has an enrichener
circuit) and that's something I intend to check... I have a new remote one
that I never got around to installing. That could very well be it...
operating it at full throttle has minimal effect, though it still makes a
big difference at lower throttle setting. I'll also replace the plugs
(even though they look fine) and add fresh fuel. All of this will have to
wait until after the holiday weekend, though. I can check the compression
but I don't know what the proper values are for this engine.

Just an FYI for anyone in the Suffolk, VA area. I will be at the VA Festiva
l of flight this coming weekend presenting a forum on painting your airplan
e with inexpensive latex paint. The forum is currently scheduled to run fro
m 11:15 to 12:15 on Saturday (maybe Sunday too). I will talk about finishin
g my Kolb MKII, Titan Tornado, and Pietenpol Aircamper. Weather permitting
I will have the Titan with me. Stop by and say hi if you get the chance. Be
low is a link to the festival=99s web site.

But an air leak would cause a lean condition... all my symptoms point to
rich running.
