Hello to all,
I'm finally completed the reconstruction of my Mark II.
I'm Italian and I am speaking little English.
I wanted to ask a question.
If I put on the wings the VGs, the speed cruise increases or decreases?
Thank you
Charly

I am going to step out in defense of the ole 202 cuyunna engine. I have had
three of them and I want to tell you this: I have never had one go out on
me or fail me because of something it did. It was all ME. I pushed it too
hard, bad fuel, lines, squeeze bulbs, plugs, argh. I have however, had the
supposed good ole rotax stop on me. I lost a crank with no sign of failure
and no real reason, it just seized. One of the little bearings was square I
guess and it went to lunch and took its buddies with them. I have had a
lots of fan belt problems with the rotax but cooling with the 20II was no
problem if you just kept it in its envelope. Never, I repeat, Never try to
outclimb a rotax with a 20II cause it is not the same and wont do it. So, I
guess apples and oranges. If you treat any engine correctly and stay within
its tolerances, you should have good luck with them. We are our worse
enemies. Ted Cowan, original firestar 447, kobra cuyunna, pterodactyl
cuyunna. Slingshot 912UL. By the way, I might have a fix for the rum rum
of the 912. I have to experiment on this concept and let you know. If it
is it, many will appreciate it. It might not be what we all throught it
might be. (hey, sounds like life, huh.)

properly built Kolb with a qualified pilot doesnt need VG's>>
Hi Ellery,
2 points. From the flying point of view I don`t think anyone has claimed
that you NEED them. They just make things a bit easier.
Second point. In the UK with an Xtra you DO NEED them because you will
not be allowed to fly it as a microlight without them. With no VG`s you
cannot get the stall speed low enough to fit into the formula which must
be met to qualify as a legal microlight.
Horses for courses?
Cheers
Pat

you will not notice any difference in the cruise but the stalling speed will
be lower by about 5mph

Bubbling at the fuel filter: It could be an air leak, especially if you
use the screw type hose clamps which don't always seal all the way around
small tubes. Better to use safety wire. A bit of bubbling when the engine
is first started is normal, as any air and vapor in the line works its way
through. However, if there is any blockage upstream (happened to me on my
first flight in the US, a bad primer bulb), the suction can cause steady
stream of bubbles as the fuel boils into vapor.
Re sputtering: Not clear from your description. Is it running OK at full
throttle once it clears out, and do the plugs and EGT look OK? If so, it's
likely it's loading up at lower throttle settings, could be the needle clip
(raise the clip to lower the needle and lean out the midrange) or idle
adjustment screw. The jettings listed in the Cuyuna manual (they give a
chart of jet sizes according to altitude and temperature) are a good place
to start. Using fuel with ethanol may shift it slightly lean, so you may
need to go one jet size larger.
If the crack in the prop isn't too bad, you can fix it. Spread it slightly
and squirt some wood glue (yellow carpenter's glue) into it... then balance
it afterwards. I've seen some amazing prop repairs in the PPG world; some
of them go too far, I think, but they hold together.

I have the bulb above the fuel filter ( the bulb is brand new from Aircraft Spruce,
the original was rot cracked, plugs are also brand new), and we did not
install it with hose clams at all. I have already taken care of that now. I have
it installed Fuel Tank, filter, bulb, pump, I also have yet to run the motor
to check and see if the problem is solved. All that stuff happened yesterday.
The bubbles start right at the fuel filter probably air was getting in that
area, and also was another bubble stream was getting in around the bulb. I think
this will be a none issue as I now have clamps there too.
-Sputtering; On take off it was good all the way to mid power, but no sooner I
cleared the strip it started bogging down I brought the power back and it seemed
to have gone away. But every time after that when I gave it opened throttle
more to get some more altitude it started bogging down again. It got to where
I could not maintain altitude about half way to where I was going. I hope its
just an air leak and nothing else, I am aware that I may have more than one
issue here, no idea about the history of this motor, even though it is very strong
when it is doing is thing at full throttle, for the few seconds that it does.
I never opened a Bing carb before and don't have the manual can you tell me about
the jetting in a bit more detail. Density Altitude around here is around 7-8K
this time of year.
If I screw the idle in is that more gas or less? Can't tell by moving it sounds
the same no matter what I do. I got it pretty far screwed in right now.

Nick -
You put a "Do Not Archive" on this post - yet I think it SHOULD be archived
, so we can search it out and re-post it when the air gets heated on-line.
=C2-
One thing (among many) that I have always appreciated about John H's posts
is that he makes it very clear that he is not giving advice, not saying "do
as I do" - just saying, "this is my experience and my preference." =C2-
It's astounding to me how much heat is generated when pilots do things diff
erently. Your post is a wonderful summation of why we should continue to le

Captain Ron:
Most folks do their engine testing on the ground, until they are satisfied
the engine will perform normally once airborne.
If I have an engine problem, I tie the airplane to my trailer hitch with a
secure tow strap. A lot safer, saves a lot of time, airplanes and people
doing it this way.

Subject: | Re: Cayuna 430 and Pterodactyl |
- Ron- It sounds like your carb is doing the same as my Bing 54 on the Ro
tax 447.- Bogging down in mid range; seems Ok at full; and air screw does
not seem to be doing anything.- Take the carb bowl off carefully, and lo
ok in the gas and bottom of the bowl.- Maybe pour the gas out through a p
aper towel.- Look carefully in the bowl, and clean with a Q-tip.- The m
ain jet is located directly under the needle that you can see while looking
in through the air intake.- If you take off the filter, the gas goes up
thropugh the main jet.- It comes out easily for cleaning or replacement.
- I had congealed goo in mine, probably from sitting.- Also, mine had a
worn out choke seal, and more goo.- The seal plunger had to be replaced.
- I got the seal plunger and a carb kit from Lockwood.- The diagram is
in their book.-
- I found very clear instructions on the web from the "Ultralight news".
- Call up "Bing 54 adjustments" on web search.- Also, Scott Olendorf ha
s a couple of tricks on his website.- No special tools required, but a to
rch tip cleaner came in handy to poke the goo out.
- John Hauck is right about tieing it down.- I was running around tryin
g to test for the bogging, and look what happened to me.- Just don't walk
into the fan.

Yes, always but ALWAYS secure the aircraft before starting. Mr. Know-It-All
here (me) once started a 582 Maxair with the throttle accidentally
WIDE-ASS-OPEN....with NO securing strap. I was standing outside the aircraft
while hand propping.
You will not believe the power of a 582 at full throttle. I had enough time
to grab the horizontal stabilizer & hang on...and that's all I was allowed
to do...hang on! It whipped me around & around about 3 times in a circle,
dragging my 190 pound butt around like a rag doll or a piece of paper! I
actually thought I could stop it in place! Haaaaaaa! What an idiot!
I got my wits together on the 2nd. trip around (I was younger then) &
while being whipped around, got it aimed at a big bunch of bushes alongside the
runway. I managed to let go at the proper time. It actually took off on
it's own & flew itself into the bushes where it (Thank God) managed to bury
itself...and still ran wide-ass-open untill I could get to it! Amazingly, no
damage but did mow some bushes with the nickel leading edge Warp Drive
bushmower propellar. No damage to the Warp either!
Always but always secure your aircraft for any runups. Sitting in the
aircraft & cranking by battery while also tied to a friggin' TREE is the best
idea for runups.

Ron,
Please put the filter after the bulb, any loose rubber from the bulb will
than be filtered out instead of going into the carb and becoming an
obstruction to your main jet.
I had this happen to me on my 503 powered Loehle SP years ago and it was a
close call. Little tiny peice of black rubber bobbing around in the float
bowel. Sounds like you better pull your bowel and check real close for
this.

Thanks John, at this point I could not agree with you more.
Now off to *my* hanger where I have all my tools, and set up, to maybe get this
contraption flight ready for 5-am tomorrow!

Captain Ron:
Most folks do their engine testing on the ground, until they are satisfied
the engine will perform normally once airborne.
If I have an engine problem, I tie the airplane to my trailer hitch with a
secure tow strap. A lot safer, saves a lot of time, airplanes and people
doing it this way.

Ron- It sounds like your carb is doing the same as my Bing 54 on the Rotax 447.
Bogging down in mid range; seems Ok at full; and air screw does not seem to
be doing anything. Take the carb bowl off carefully, and look in the gas and bottom
of the bowl. Maybe pour the gas out through a paper towel. Look carefully
in the bowl, and clean with a Q-tip. The main jet is located directly under
the needle that you can see while looking in through the air intake. If you take
off the filter, the gas goes up thropugh the main jet. It comes out easily
for cleaning or replacement. I had congealed goo in mine, probably from sitting.
Also, mine had a worn out choke seal, and more goo. The seal plunger had to
be replaced. I got the seal plunger and a carb kit from Lockwood. The diagram
is in their book.
I found very clear instructions on the web from the "Ultralight news". Call up
"Bing 54 adjustments" on web search. Also, Scott Olendorf has a couple of tricks
on his website. No special tools required, but a torch tip cleaner came in
handy to poke the goo out.
John Hauck is right about tieing it down. I was running around trying to test
for the bogging, and look what happened to me. Just don't walk into the fan.

Please put the filter after the bulb, any loose rubber from the bulb will
than be filtered out instead of going into the carb and becoming an
obstruction to your main jet.
I had this happen to me on my 503 powered Loehle SP years ago and it was a
close call. Little tiny peice of black rubber bobbing around in the float

Brad S:
That is an impressive improvement.
What was your stall speed prior to, and after installation of
VGs?
At what altitude did you conduct your tests?
What were the differences in stall characteristics prior to and after
installation of VGs?
How did the VGs affect speed at your normal cruise power setting?
Did you test stall in ground effect, before and after?
What airplane are you flying?
Would you please expand on your experience flying this airplane before and
after?
If I could get a 10 mph reduction in stall speed in ground effect, I could
land at 20 mph.
john h
mkIII - Always impressed with the dramatic improvements in aircraft
performance and handling after installation of VGs.

Same here... my original bulb was dry and hard; I replaced it with a brand
new bulb from Aircraft Spruce. The brand new bulb was bad (clogged) out of
the box. It would pass enough fuel for warmup and mid power, and let the

The point I was making is that the clamps can CAUSE an air leak, since they
don't do a very good job of clamping all the way around small
hoses. Safety wire (wrap around the hose three times, then twist) does a
better job and is lighter as well.
I would look for a blockage upstream of the first place you see the
bubbles. Places to look are the pickup inside the tank, and any fittings.
Do you have and EGT and/or CHT gauges on the engine? If so, what do they
say? If not, you should.

Sounds like my experience, except that the rpm's were surging up and down.

You have a Bing? The Cuyunas originally came with a Mikuni which is a much
better carburetor for these engines. I'm told that lots of people have
trouble getting the engine to run correctly with the Bing.
The Cuyuna manual (as well as the Mikuni manual) can be downloaded from the
files section of the Cuyuna Yahoo group (I put them there):
<http://groups.yahoo.com/group/Cuyunamotor>
You might get some more useful advice there, too, though it's not a very
active group.

Tackling the corrosion first. Remove rivet(s) sand, etch, alodine, prime,
reattach, repeat. When all joints are etched and alodined I'll do the large
parts of the structure, and then use 420 epoxy primer to seal everything.

Subject: | Re: Cayuna 430 and Pterodactyl |
Well i think I found out one problem, and it had to do with the bulb. It seemed
that the Handy dude at the ranch who forced it into the tube cracked the intake
into the bulb. When I repositioned the bulb and tried to insert it into its
new position the prong just broke off easily. Re-did the entire fuel line, found
out that I had a bulb that Kolb sent me back when I bought the kit. My buddy
who is a good mechanic came and took a look at it. We had the Carb apart (
I said Bing,, its a Mikuni written right on it) he new it inside and out cleaned
some air input and the needle closed it up. And tomorrow we shall see if I
can get a solid hour out of it. Patched up the prop, new prop will be in tomorrow
too late for the AM flight.
Other than that will see what happens.

Same here... my original bulb was dry and hard; I replaced it with a brand
new bulb from Aircraft Spruce. The brand new bulb was bad (clogged) out of
the box. It would pass enough fuel for warmup and mid power, and let the
carb bowl fill, but at full power the it couldn't keep up and the engine
would starve for fuel shortly after takeoff. I discovered this the hard
way on my first flight in the plane; fortunately it would make enough power
to get around the pattern and land. I now have a plunger primer and no
squeeze bulb.
