G'Day All,
I removed the smoke nozzles from the 18 T to replace with smoke nozzles
with a smaller hole to try and get a little bit more duration with Smoke
on.
The right hand nozzle was clean and free of any deposits.
The left nozzle had to be pried out of the exhaust as it was deposited
with very light grey carbon which may indicate lean burn.
Right hand exhaust good colour, left exhaust lots of very light grey
carbon.
Can anyone please explain this?
I have attached photo to show smoke. It really pumps it out.
Thanks and cheers,
Chris.

WAG here. Could it be that the cylinders on the left side are further fro
m the carburetor in relation to the rotation of the super charger?
I've never thought to look at this before.

It is possible it is a lean burn. Did you pull the plugs and compare
left to right? You may want to remove each of the exhaust sections and
look in the individual tubes to see if one cylinder is more gray than
the other. Be sure to check each intake gland nut and intake collar for
security. They must be completely tight. It is also possible one of
the intake gland nut seals is deteriorated or damaged which would permit
air to be sucked in and lean that particular cylinder. Just my 2 cents.
Dennis

If you have access to a Housai manual, it provides better instructions as it
has a diagram. The difference relates to prop gearing. I have reset mine
twice after engine disassembly and it's not a big deal.

GOOD FOR YOU! Good job in finding the proper task cards!
Let me run my mouth one last time. First, adjusting this thing is a real
pain in the ass. It is hard to get to the nuts and stuff to remove it, it
requires you to get the engine set up perfectly, and then insert the thing
back in and tighten it down. I have been involved in adjusting it twice,
and it was a real ass kicker.
Next... make darn sure... let me correct that: MAKE DAMN SURE that you know
this is the problem before you remove it from the engine and start trying to
re-adjust it. Once you remove it, you have no choice but to finish the job.
I am not kidding when I tell you that a flow restriction in the air system
will cause the exact same problem that you are reporting.
Yes, it is most likely that someone messed with this in the past, and just
could never get it right again, and this is what you have wrong now. (I.E.
A misadjusted Air Distributor) The odds are good that this is your problem,
but as a Tech Rep, my mind always considers the alternatives and you can
never rule out ANYTHING unless you verify it as a "known good". That said,
if your AIR FLOW to this unit is low, it will do the exact same thing you
are now reporting.
That said, if I was there, I would take my nitrogen bottle with a good
regulator and would connect it DIRECTLY to the line going to the air
distributor and would set it to 730 PSI and would see what happened when I
turned it on. If the engine does the exact same thing, then you are sure
that the distributor is the problem. However, if the engine spins right
around perfectly, then you can STOP RIGHT THERE and say "BOY OH BOY IT IS
NOT THE AIR DISTRIBUTOR" and you have saved yourself one HUGE amount of
work.
Consider this advice carefully.
Best regards,
Mark Bitterlich

OK people, time to be Russian for a night. Wear something Russian and bring
something Russian as we celebrate the first man in space and the Yak 18 tha
t
started it all for him.
Party is in hanger 12 and will start around 4 or 5 or 6 depending on
weather we are flying or not. Either way come down when you can and enjoy
some vodka and watch some Russian videos
And if you are lucky sit in a real Yak 18 for a photo
Just to clarify its Sunday the 11th at Hanger 12 Bayport (23N) from about
5pm onward

Don't run me up the flagpole and disc me please, but-could this be LEAD a
nd not carbon?- The dynamics of airflow on the Russian aircraft impacts t
he evacuation of the exhaust and the velocity that ends up exiting the tube
s.- Lead is in a gas state as is leaves the cylinder and will revert back
to a solid as soon as it sees enough of a temperature shift.- It might j
ust be possible that all you are seeing is normal lead precipitation-due
to a slighter cooler exhaust on one side more than the other.- Lead is no
rmally grey in when it reverts back to a solid from the exhaust.-
-
This is just a pure wild ass guess.- But if the engine has time on it, is
running properly, and has good compression, I would not get too upset abou
t this.- If you want to get serious, get a borescope and look inside the
cylinders.- Look very carefully at the exhaust valve.- If the engine is
running lean on one cylinder or more, you'll see it.- But again my WAG i
s that this is nothing to worry about.-
-
Flame retardant suit now in place.-
