I was just taking the cuyuna UL II-02 out of my Kolb Ultrastar last evening and
preparing to put in the spare Cuyuna 430 that came with the deal.
The UL II-02 had a probable seizure on the #1 (PTO side) cylinder.
Examining the piston and cast iron liner its amazing how the piston top by the
exhaust port had melted and eroded and that whole exhaust port side of the piston
just lost its metal onto the liner wall making one hell of a mess.
The rings were intact but frozen in that side of the piston.
I was trying to dtermine if I could hone the liner smooth again, but it just looks
like an awefull mess and I think I better replace the liner.
Anyone know how to remove a cylinder liner from a Cuyuna UL II-02?
When replacing Pistons, is that normally done in pairs or can I do just the seized
one?

Subject: | Ultrastar Wing folding |
Now that I have my US home and am getting her ready to fly again, I did some reading
and it was written somewhere that the newer US fold the wings back from
the rear spar attach point???
It said that this was done to that the wing did not sit so high and would fit in
the garage.
I just cant see how this would work unless the wing leading edge was down on the
floor side?
Can anyone enlighten me on the correct info...it just seems wrong.

On my US, I welded a tube cross member to the airframe just about a
foot or so down from the current front spar attach point.. It was
designed to protrude the same as the front spar carry through.. The tube
dia was such that the square wing fold hinge fitting would slide on and
then could be held with a pin of the same type that holds the wheels to
the axle.. bolt, pin etc.. This dropped the wing enough to fit into my
garage.. Herb

The ugly mess of aluminum on the wall needs to be etched away by using
muratic acid before you get too concerned about the liner.. That will
give you a better view of the damage the rings may have done ..
Careful...I use long q tips and eye protection.. Herb

Anyone out there flying a Hirth engine?
Here's the deal, guys. I have a Challenger II Clip Wing in the hangar that
I'm supposed to fly to PA next week. I have absolutely no experience with
the Hirth and the thing is unsettling to say the least.
I could not, in the hour I've flown it so far, keep the CHT and EGT alarms
on the Stratomaster from going off. The CHT alarm is set for 500 degrees and
the EGT at 1300.
Yep, you read those numbers right.
I took it around the pattern three times before a short cross country
flight. During those, I could keep the CHT's under 400 in climb, and they
came right back down when I cut throttle at the threshold on down wind.
After I completed the roll out they were back down to 250 or so.
When I flew over to my friend George's house, about 15 miles away, the CHT's
were running 512 and 549 and the EGT's were 1225 and 1252 by the time I over
flew the pattern back here at home.
The engine will not hold a throttle setting. The owner had attributed this
to throttle linkage that wouldn't hold, but I kept my thumb on it the entire
flight and I know the throttle did not move, at least on my end of the
linkage. It never throttled up, once a setting was made the RPM would not
climb uncommanded, but it would bog down several hundred RPM with my thumb
holding the throttle in place. A tap on the throttle would bring it back up,
but then in a few minutes it would bog again. A couple of times I would have
sworn it was going to sieze, but it responded to the throttle and came back
up to nice smooth running again.
I've got a feeling this POS is going to PA by trailer at this point.
Did I mention I had the stick almost full forward the entire flight? I'm
only 20 pound lighter than the owner and I would swear I had all 20 pounds
pushing forward on the stick the whole time in the air.
After today, I really LOVE my Kolb and Rotax.

Sounds like two cycle engine abuse. Why didn't you put it back on the ground and
raise the needles? Are you trying to give Hirth a bad name?

Thanks for that tip about the acid.
I was thinking that the cylinder liner would be a lot harder than the aluminum
and is probably servicable after removing the aluminum and honing a bit.
Now I just have to find the acid.....Home Depot carries it?

A small step. I finally have my Mark 3 repaired and back in my hangar.
Just about a year after my driving it into a barn.
Now starts the re certification and testing process.The PFA has ruled
that as a major portion of the plane has been replaced, the port wing
and the complets cage, it should be treated as a new plane and start the
checking from scratch.
Heigh ho!. Still she looks very smart and the girlie art looks good.
Cheers

Rich,
In addition to richening by raising the needles as Jack suggested, pull
the air filters off and make sure the carb slides are opening at the
same time. Close the throttle all the way and put a long sharp pencil
under the lip of both slides so they are inline with each other. When
the throttle is opened the pencils should move exactly together.
By the sound of the trim issue, even if you solve the rough engine
problem, I don't think I would fly it either.
Where in PA is it headed?

How 'bout posting a pic of the 'girlie art'?
Hi Russ,
i think that is pushing the envelope of my computer skills but I will
try. Planning to run the engine tomorrow if the promised weather window
materialises. I think that is pushing things as we have had a reasonable
day today which enabled me to get the plane here on an open trailer and
the way the weather is at the moment two consecutive days without
pouring rain is too much to expect.
You may know that a large swath of the middle of England is under
floodwater. thousands of homes are flooded with people sleeping in
schools, council buildings etc. Thousands are without drinking water.
Millions of litres of water have been distributed and there are bowsers
on many city streets. It is going to be months before some of the houses
can be reoccupied. More heavy rain for my area is forecastr for Sunday.
Greece and Italy are having fires ignited by a ferocious heat wave and
people are dying of heatstroke and dehydration. My brother in law was in
Gambia in May and the village he stayed in is now under 4 ft of water
from torrential rain.The weather seems to be cocked up everywhere.
Heaven help a sailor on a night like this.
Cheers
Pat

Jack, According to the previous owner, this aircraft has made several multi
hundred mine cross country flights, so I'm not sure a 15 mile cross country
counts as 2 stroke abuse. Had there been an airfield or anything I thought I
could have done a precautionary landing in without risk to the aircraft I
would have most happily done so. In a conversation with the previous owner
this evening he told me he sometimes sees CHT's as high as 480 on a long
climb. Wish he'd told me that, rather than all the book values he gave me
for engine parameters. Oh, well.
As far as Hirth goes, the market place has spoken, as all the talking head
economists on the noise say.

Now you are really getting close to our neck of the woods. 08N
Keller Bros is a nice Ultralight friendly airport just west of Reading.
Please let us know when you pass through central Pa and if we can be

I have a Mark III C and I just purchased a 912 ULS to install on it. I

Also what prop are you using?
Prop extension?
