| Subject: | Seized upon some blackberries... |
Sunday after church, Dave called and asked me to bring the Firefly over to his
place that evening, sounded like a great idea. Took off at 5:30, beautiful day,
light bumps, Firefly was flying great. Then the engine quit - at the worst possible
place, and Big Dummy Pike was flying too low to make it to anywhere other
than a giant blackberry patch on the side of a hill. Only got one picture
of the aftermath, the guy in the picture lived just over the hill and came to
help. Got it loaded on the trailer and home by 9:15 that night.
Piston was seized in two places, I am thinking that using a Free Air 277 in the
pusher configuration is a bad idea. Since I have to taxi uphill before takeoff,
it probably gets the engine too hot and then you have to heat it up even more
when you takeoff. Or something like that. The plug looks good, the EGT was
staying between 1050 & 1100, fuel was fresh & had the right amount/kind of oil,
so - who knows?
Bent the gear a little, we straightened them today. Bent the fuselage forward tubes
a little, will cut off some fabric and straighten them tomorrow. Then will
need to patch a few cracks in the nose fairing.
Oh well, it actually turned out pretty good, I always ask the Lord to protect me
prior to each flight, and if I had not had my left hand still wrapped around
the throttle lever (like that was going to do any good!) I wouldn't have even
got a scratch. Instead, the back side of my left hand found the blackberry bushes
immediately upon arrival... ate me up!
What was really funny, I had a Dr. appointment Monday morning with my regular family
Dr. that I have had for 25 years, he came in, took one look at my left hand,
and said "What have you done now?"
Me: "I landed the ultralight airplane in a blackberry patch."
Him: "Why did you do that?" We had a good time... [Laughing]

Sorry to hear of your difficulties. Been there, done that myself- three
times to date. Like you, the only time I got hurt was when I held onto the
throttle while in the process of "crash landing". Mine consisted of a
sprained middle finger. Apparently your finger needs to be pointing
somewhere else when hanging upside down. Actually looks pretty good for
what happened. Pride always takes the worst hit. Hang in there. :-) And
watch out for those nasty throttles.

Hey Richard, I=99m just happy that you=99re ok. Airplanes can al
ways be repaired or replaced. I=99m glad you walked away. Free-air may
work fine on tractor drives, but questionable on pushers. I seized a brand n
ew 377 many years ago. Fortunately I was at 2000ft AGL right after takeoff a
nd easily glided at to the airpark. Psalms 19:1

4130 tubing did what it was supposed to do, protected the pilot. Had it
been aluminum it may have been a different story and done some damage to the
pilot. You did a good job. Glad you have no more injuries than some briar
scratches.
Was that the intake or exhaust port in the photo? If it is the exhaust
port, I would venture to say you were running way too lean. I think you
should show soot and carbon, a little black and some brown on the piston and
the exhaust port. Through all these years I have come to realize that our
ultralight instruments are not precision instruments and not instantaneous.
I'd be more inclined to go with carb set up the way it comes from the
factory, prop correctly, and forget about the EGT gauge. Usually you never
get a warning until after the two stroke has seized. Only takes a micro
second when that slight film of oil breaks and the seizure takes place.
Fuel cools and oil lubricates.
I have also heard free air two strokes don't cool well on pushers.

Thanks John, I could not remember so I went down and looked at it, it seized on
both the intake and exhaust side, but I noticed something just now that did not
register earlier: (a lot of things did not register earlier - I got overheated
working on it today and the brain was in slow motion) there is a vertical
gouge on the cylinder on the intake side caused by the top rings at the point
where they meet. I will pull them off tomorrow and check for end gap.
The engine came with an invoice showing a fresh overhaul from Lockwood several
years ago, and had (supposedly) never been run. I guess I should have pulled the
top end off and checked it, but did not.
It is still a little early for much carbon or soot, only got about 12 hours on
it. And Phillips Injex (which I prefer to Pennzoil) is not near as sooty and dirty
as Pennzoil. It is jetted almost exactly as the factory calls for, the needle
is 1 slot richer than spec.
We are in complete agreement on setting up an engine; jet to factory specs, set
the prop to just nudge red line in level flight at full throttle, and use the
egt to monitor things.

IIRC each ring has a stop pin to keep the rings from rotating. Hopefully,
the gap was not in line with the intake or exhaust port.
Many years ago a well known racing engine builder, Bobby Norwood,
Montgomery, AL, did all my ROTAX engine machine work. Once I asked him how
to get the two stroke to burn cleaner, I was concerned with the soot and
carbon on the top of the pistons. He told me that was good, in that it
provided a thermal barrier and kept the pistons cooler. Never doubted his
word or did any research on the subject. After that I never worried about a
little carbon on the piston.
Might want to mic the piston and cylinder to insure they are round and not
oval.
Another thing I just noticed on the engine pic. I don't think the ports
were chamfered. If ports are not chamfered it leaves a sharp edge to catch
a ring or might even cause a break down in that micro coating of oil.
