Subject: Yak-List: What's new in the parts room?
Fellow CJ and Yak Drivers,
This will be the first "What's new in the parts room posting". This posting
is designed to keep you up to date on new parts arrivals, mods and specials.
It is the time of year when conditional use inspections are scheduled. You
might consider our newly packaged Conditional Use Inspection Kit which
contains all of the fuel gaskets, oil gaskets, compressor filter, and felt
wheel seals normally changed at this inspection. It also contains a fresh
desiccant refill kit. Price $54.00 per kit.
New in stock:
Engine Baffle pads P/N 14.36.580 (8 per set) and P/N 14.36.581 (9 per set)
400 X 150 tires (nose gear)
400 X 150 Tubes (nose gear)
Rocker shaft crush washers P/N 14.07.511
285 hp engine mount rubbers P/N H2-6400-04 8 each (16 per set)
M14P engine mount rubbers P/N H2-6400-04-M14P (16 per set)
Exhaust valve 285 hp P/N 604.04.04 These are VERY hard to find, last
shipment sold out within a week.
What's NEW:
Mod kit to use 285 hp shutters on M14P engine installation. Huge cost
savings over Yak 18 shutters if your converting to the 360 hp M14P.
Mod kit for QL-17 snot valve, stainless steel needle and hardened brass seat
solves the rust problems.
What's Coming:
Stainless steel 3 port QSF2A flap and gear valve for both CJ6 and Yak 52
2 Week Special:
Red Silicone rocker gaskets (flat type) normally $4.50 each. Special price
$4.00 each Special price ends 12/19/11 or while supplies last.
Best Christmas wishes from Omak,
Doug and Kathleen

MotorstarNA stocks the M14P motor mount kits. They include all new rubbers
pieces, washers, bolts, nuts and cotter pins. The kit is P/N 506400KIT and
sells for $475. Note that the two rubber mounts that are behind the magnetos
are different from the rest of the mounts.

For what? In order for EGT to be useful you need to know what you are going
to do with it. First you have to understand that EGT readings are relative
and not absolute. What the number is doesn't matter unless it is reading
TIT and since none of our planes are turbocharged, you aren't going to have
a TIT anyway. So the only way for EGT to be useful is if you have a way to
vary the mixture.
As far as I have been able to discern, there is no use for a single-probe
EGT unless you know for a fact that all cylinders have been matched for
mixture. If not, you need a 9-probe EGT to be of any significant use. If
you are running an M14P which has automatic mixture control, there is
nothing you can do with the EGT readings except maybe use them to determine
that you have one fouled plug. Huosai engines have a mixture control but I
found that the single-probe EGT I had was not particularly useful in
setting mixture. I had more luck setting mixture by ear. My attempts to run
Lean of Peak (LoP) were not successful with the Huosai because the engine
would surge, probably from a poorly adjusted carburetor, most likely
because the mixture would change with flow. (Overly stiff diaphragm in the
carb? Not sure.)
But let's say you do have an adjustable mixture, i.e. Huosai, M14P with a
manual mixture modification, or Airflow Performance single-point FI. In
that case you are looking for a good 9-point EGT system with either
low-mass, fast-response probes (you want grounded probes with differential
input to the display), or a display system that projects future EGT based
on probe thermal lag response and rate-of-change of temperature. I am
pretty sure that JPI fills the bill on this one.
I know, you asked the time and I came back with a discussion on building an
atomic clock. Sorry. The problem is, once you get it you have to be able to
do something with it. Adding another gauge to the panel for something you
can do nothing about is a waste of money, panel space, and your pilot
workload when you are flying.

Actually I was asking because the plane I picked up still has all 9 probes
/ cabling intact and in-place, AND an open hole in the panel. But thanks

Well, the right answer is to install the same unit that came out so that
all the cabling will work. Do you know what was there before? Since there
are only a couple of companies making 9-probe EGT units, you can look at
the part numbers on the probes and check with the manufacturers to see if
they are their probes.
Good luck!

Linux is good. Personally I prefer MacOS. It has all the joy of Unix
without the incompatibilities that come with new libraries every year. ;-)

So, yes, having the EGT readings can help if you have a bad plug or wire.
It can also tell you when you left the primer cocked over/open and it can
tell you when you left the intake drain open. It immediately tells you when
you have a Cyl problem. I think it is worth the installation as it saves
time/cost in troubleshooting problems.

A rough running engine will tell you all that too! A simple check with
a laser pyrometer ($80) will tell you which cylinder is cold on mag and
plug issues. Primer and intake is easily identified by rough idle and
visual cockpit check. If you don't have a way to lean the 9 probe egt
is pretty useless.
