| Subject: | Beware of scammers working the list |
Indeed, be very careful.
I recently also had someone bidding for my Yak, a certain Mark Simpson (!)
from the UK. It looked OK at the beginning, but soon I realized that
something was wrong. After some investigation by good friends in the UK, it
turned out to be a gang of Nigerian thieves, specializing in the more
expensive goods (boats, planes ...).
BR,
Jan

Subject: Yak-List: Beware of scammers working the list
Gang,
Below is an email from a guy purporting to have Yak parts in the UK. When I
pressed him for photos, he balked. And of course the price on the part
requested is WAY off. He is clearly a scammer. Just a heads up to be
careful out there....
Happy Flying,
Barry

Have you pulled the little finger screen on the right side of the nose
case forward of the prop governor to make sure it completely clean?
With the RPM going up and down, it sounds like it might be in the prop
governor. But before you R&R the prop governor, check the finger screen
and also make sure your prop hub counter weights move freely when the
prop hub dome and piston are removed. When was the last time you
removed the blades at the castellated nuts and cleaned and repacked the
prop hub bearings?

Subject: Yak-List: The Surging Continues....Help
Here are my symptoms. It's 54 Degrees outside and my Chang surges in
the climb and once I'm level at 5500 I started messing with it so I can
explain whats wrong.
Once level the surging is more prominent when I ease the throttle
forward, almost as if it wants to cut off but catches again. My
Manifold Pressure stays the same, however the RPM is going up and down
along with the surg.
I used one hand and held the Prop forward and pushed the throttle
forward again and it surged again but not as bad as without holding the
prop forward.
The prop seal was changed 3 weeks ago, that might be it or could it be
my Governor going bad?
Also when I landed I throttle forward and it just about died...So I
got this crazy idea and left the primer in the up position and shove the
throttle forward and it seemed ok. I did not do that in flight.......
Any thoughts, be gentle mit me plz, It's my second time posting.
Thanks

Interesting. "Mark Simpson" tried to buy my Legacy...being a broker you get lots
of scam attempts, but as you say Jan, Mark was much more sophisticated. It
came down to running searches and making him verify information. He even sent
back a "signed" purchase contract from his customer (who came up legit in a
web search), but in looking at them closely, it was obvious the signatures were
fake.
Bottom line is make sure you protect yourself!

| Subject: | The Surging Continues....Help |
The other places to look are the carburetor diaphragm, the primer lines to
the super charger, seals on the primer, primer/ system line connections,
system/ primer lines, prop governor cable attachments, the copper sleeve
guide, the c clamps on the fuselage from the lever to the governor, fuel
filter screens, fuel lines for flappers, fuel lines for leaks, fuel pump for
oil leaking through the seal between the oil pump and the fuel pump and
intake collars at the cylinder and the super charger.
Since I have a YAK, I'm not sure what you mean by leaving the primer in the
up position. Since in the YAK, the up position is the center neutral
position that closes the ports so fuel cannot pass through to the system
side or the primer side. If leaving your primer in the neutral position does
not recreate the problem, then it comes down to are you getting air in the
line somewhere. The 50 and 52 's primer hand pumps are reversed on
position. Centered with the indicator up at 1200 o'clock positon isolates
both sides (turns off both sides). Leaving the knob turned to the system or
the primer side could cause the engine to run rough.
Another place to check is the cables to the prop governor along with all the
c clamps that anchor the copper sleeve the cable slides in to the fuselage.
That also manifested itself as a wondering prop RPM. I could not get the
prop to fully cycle back to 51-55% during run ups and I would have the prop
rpm increase in a dive. That was a different problem from the surging
experienced at 5500 ft when the power was pushed up. That was solved by
replacing the carburetor diaphragm. In cruise, there seemed to be a
variation in power (surging) with observed variations in the RPM by 5% or
so on the gauge. When I pushed the power up to 100% at altitude, the engine
balked and sputtered nearly quitting but eventually came up to power. It
seemed to like 70% better than 80%. That has resolved with changing the
diaphragm.
I had something similar with a flapper in the fuel line from the "sphere"
fuel flow equalizer to the carburetor. We found some 1/2 cm to 1 cm hose
fragments had clogged the finger fuel screen at the carburetor. Understood
the Chang does not have a carburetor filter screen.
After all that, I also changed the springs in my prop governor still chasing
the surging problem. That did not solve the problem either.
Even went so far as to change the prop governor itself. That did not help
either. Pulled the dome on the prop and checked the seals with no help there
either.
Found an interesting case of Russian Afro engineering as it pertained to my
prop governor cable while chasing this "surging" problem. Instead of running
a one piece copper tube for the sleeve, they ran two segments. The two ends
were anastamosed inside a larger bore piece of tubing held together with a
lone c clamp. Over time ( 146 hours since taking delivery), the c clamps on
the fuselage had loosened up allowing the cable guide end from the
anastamosis segment forward to the prop governor to migrate forward. So now
the cable would form an S curve between the two ends where a gap between the
two copper tube guides were now. Fixing that required pulling the Aux and
main fuel tanks out of the 50 and repairing the guide tubing. After doing
this, I have not had any surging sensations or variation in the % RPM on
the gauge.
That is just some of the tribulations I have been through with my 50 while
chasing a "surging engine".
So here is a list of what has been done to solve the surging problem or the
varying fluctuations in % RPM (by me-call it the shotgun approach over a
span of 2 years as different parts of this equation have arisen):
Pulled the carburetor only to find the fuel filter screen had fragments of
the inner liner from the fuel line in it and could have been cleaned without
pulling the carb. This came after the engine quit 50 feet off the runway on
take-off resulting in a dead stick landing without damage to the A/C or
myself. Funny thing, she started and ran fine back in the chocks with the
exception wanting to surge at 80-90% when run up. This was done with the
aircraft tied down and chocked. Losing the engine came without any prior
warning.
Replaced the primer lines after finding a small leak in the line at the base
of the fitting at the firewall connection
Replaced the fuel pump after seeing a mixture of oil and fuel drip down on
my knee from the overflow valve while I was under the aircraft tightening
the intake collars -seems the seal on the driveshaft was leaking allowing
oil to seep down into the fuel pump. Had seen blue oily drops on the drop
pan under the chin of the plane earlier but could not find a source. The
drop pan was in place under the nose to prevent oil from collecting on my
hanger floor.
Replaced the o ring seal on the primer after fuel leaked out during priming
that was not solved by tightening the knurled nut.
Pulled the prop governor-replacing it with another along with changing out
the springs for the stiffer set offered by Jim Kimbell
Replaced the seals on the prop dome and piston - Bearings had been service
the previous year.
Pulled the finger screen in the capillary line to the prop - was clean
Screwed with the idler arm on the prop governor because I could not get the
prop to fully cycle after calling myself checking all the cable attachments
except for the one I did not know about. The Russian Afro engineered one
below and behind the fuel tanks hidden from sight. Did not find that one
until the very last when I was trying to advance the cable end by pulling
back on the prop lever. Seems the cable only moved about an inch. That sent
me on a chase through the fuselage from the governor back to the prop lever
attachment at the consol in the cockpit.
Lastly repair the copper cable guide and tighten all the c clamps holding
the prop governor cable. Then put the F@#$%^& fuel tanks back in along with
re-attaching the lines making sure to use fuel lube on the threads. Making
sure none got on the nipples so I would have an airtight seal without
gumming up the fuel screen filters. ( Oh yeah, I pulled those and made sure
they were clean too.)
This along with checking and tightening any loose collars on the intakes at
the cylinders and the supercharger.
Also tighten any loose exhaust collars. A couple of each, intake and exhaust
collars were found to be very slightly loose.less than a quarter turn. Doubt
that had anything to do with the surging.
Now having done all that, I have not the foggiest idea what solved the
problem but it is gone.for now.
Not sure I would spend much time flying her if she is surging to the point
of losing power in flight though. I've been a test pilot enough over the
past 6 years.
Good Luck.

Hey all;
My wife is trying to get a start on e-bay and has put on 28 Russian plugs I had
hanging around. She'll be putting a 5th and 6th seat for a Baron (I think they
will work for a Bonanza also) later today. Please don't be afraid of the plugs
they are new as advertised. If you want/need some you can help the little lady
get her first sale.
Thanks a lot.
