I fly routinely in Northern Illinois and Southern Wisconsin in the extreme c
old months of January and February. During these months in the event that a
go-around is necessary, I and my teamates have found that=C2-applying carb
heat on final helps to keep the engine from stuttering. I think Brian maybe
right that after a low power setting the carb may cool a bit and the carb h
eat warms it enough to allow for better atomization of the fuel when dumping
all that fuel in rapidly.

There really isn't a need for carb-heat in our engines. In a standard carb t
he fuel is metered into the venturi which is upstream of the throttle valve.
As the fuel evaporates it cools the air causing the moisture in the air to
turn to ice. The ice usually forms on the throttle valve.=C2-
=C2-
The pressure carb is really a single-point fuel injection system. The fuel s
praybar is downstream of the throttle valve and there is nothing between the
spraybar and the compressor impeller. There is no chance of ice ever formin
g on the compressor impeller.=C2-
=C2-
So the only time you really need carb heat is if the inlet itself ices up (r
equiring alternate air) or if it is so cold that you need extra heat to get
the fuel to vaporize when the engine is first started.=C2-
=C2-
Are there any other times? Probably, but I can't think of any.=C2-

Brian and Pappy,
It all boils down to a matter of choice and options, with a 308 you have
few options. A model 12 Winchester pump gun is my favorite to carry in
the Cub. Stay away from the auto loaders, to many moving parts. If
your in bear country (remove the plug) load it slug X 4, and then 3 dbl
0 buck, total of 7 rounds. Just hold the trigger back and pump it.
There is no bear alive that can stand up to that kind of punishment. Or
if your trying to knock down a grouse for dinner take along some #6 duck
loads. This advice was given to me many years ago by one of the oldest
(and still alive) bear guides in Alaska.
Always Yakin,
Doug

Ah, good point. Not being a shotgun man myself I tend to forget that
option. For taking care of yourself it is hard to beat a pump-action
with alternating 00-buckshot and slugs. If the 00-buck doesn't stop
them it will certainly slow them down long enough to do the job with
a slug.

| Subject: | Re: Mixture too rich? |
I have a JPI FS-450 Fuel Flow in my -50 and it is accurate to about .2 Gallons
at the end of a long flight, so I am confident the flow values are correct.
At takeoff I get around 40 gph.
At 82% and full throttle around the 3000' to 6000' range it is not uncommon to
see anywhere from 25gph down low to 20+ up higher.
On a recent long cross country with low power cruise at maybe 70% and throttle
back (actually to about adjacent to the prop lever seems to work well) we were
consistently under 15gph, and more like 13 to 14.
I have my mixture trimmed pretty lean at idle, down to under 2.8 gph at 40%.
Like many M14s, mine will sometimes stumble when putting in throttle slowly from
idle. You can watch the fuel flow spike from idle flow under 3.0 to about 13gph
when it stumbles, then back to the stabilized flow once it settles down.
The computer in the FS-450 is linked by a serial bus to the GPS and knows where
we are going and when we will be there. It also computes MPG and I get about
11 Nautical miles per gallon. Mostly useless trivia I suppose.

week. It was my first flight in one...impressive, what a machine!
My question is what have -50 owners done to extend the ferry range? The one I
flew held 34 gallons. Is that about the best one can expect for fuel?

The amount of lead in 100LL is NOT almost nil. 100LL has 3-4 ml/gallon and
that is a lot.
Mon, 12 Nov 2007 19:08:44 -0500From: vectorwarbirds@aol.comSorry it took s
o long to reply, just back from the Nellis AFB show. As I said we have bee
n running mogas in both the CJ and Yak for several years now. The CJ was d
esigned to run on 70oct so 87 is not a problem. The amount of lead in 100L
L is almost nil, but since we cannot always get mogas and all the airshow s
erve 100LL we get enough of that to put our 100LL to mogas ratio at about 5
0/50. I have had two jugs off now for leaking base gaskets and have inspec
ted the valves for unusual wear (old race car mechanic I was) and have foun
d no difference between the engines that run 100 vs mogas. The bigger probl
em I think is people not taking the time to set each valve four times when
adjusting the valves and then ending up with a tight one and then burned.
So like I said we have been happily running along now for about 2000hrs tot
al on regular old 87 oct without a single problem. Be advised tho that you
ca nnot run ethanol or really crappy gas. We use the Peterson Mogas STC f
uel tester when buying gas out and about. Once we have found a local stati
on that we could test several times as good we just stick with their fuel a
nd only test once a awhile. NO ETHANOL THO it rots the rubber hoses from t
he inside out. We have never found an airport that had ethanol in the fuel
they sold.The engine runs better as 87 oct produces more power than 100LL,
remember that our 6:1 compression ration engines don't need hi octane fuel,
so that is just a waste. We see cleaner plugs (auto plugs now) and just
a tag lower cylinder head temps (have a nine cyl gauge). One thing we do,
and I can't really say why, is that we do run Marvel Mystery Oil in the fue
l, I just dump in one quart per 90 gals of fuel in my truck tanker and let
it go at that. I don't know if it really does anything but I figure it can
't hurt the valve guides to have a little oil running around. Its only abo
ut 2 bucks a qt at Wal mart so what the hell.So thats my two cents, I have
put over 4000 gals of mogas through my CJ engine with nary a burp, in my wa
rped mind that is $6000.00 in fuel savings over 100LL. Thats buys a lot of
Rum my friends!!Email me if you want any further info on my truck tanker s
et up or mogas use. I also have a web site that lists all the airports tha
t carry mogas, many back east but few out west. I did tho fly all the way
to Sun and Fun and back on mogas, which was never over $2.88 a gallon!!Rega

| Subject: | carbon bonds (was: mogas vs 100LL) |
You lose sleep over things like that? Sheesh. The amount of energy libera
ted, the temperature produced, and the speed of the deflagration/detonation
are three independent characteristics. Nitroglycerin, for example has a v
ery high speed of combustion, but a rather low BTU content. Acetylene has
a C-C triple bond and produces the highest combustion temperature (aside fr
om the 'observed', but unsubstanciated diatomic hydrogen combustion).
You are correct that octane is measure of anti-knock characteristics. It i
s not a measure of BTU content (energy). Good luck in convincing people of
that though. Billions have spent on advertising to convince the public ot
herwise. Using a higher octane gas than an engine needs is of absolutely n
o value. Higher grades of gas may have more additives that do something go
od for the engine (or may not), but that isn't what octane measures. There
is something called octane creep, wherein an engine needs a higher octane
fuel as it gets older, related to the fact that it is more prone to pre-ign
ition due to deposits in the cylinders. Marvel Mystery Oil may help... or
maybe not. I believe MMO's usefulness is in preventing varnish in the deli
cate little parts of the carb.
But I digress. Your points were all correct in your previous post.

| Subject: | Hard starting CJ |
Hi All!
I went to fly my birdie tonight only to have it not start, and act very strangely
in the process.
The pre-start pressure was around 40-45atm, and for the first few seconds during
the start the prop seemed to be swinging at it's usual rate. Very quickly though
both the prop rpm and the main air pressure dropped; the bottle showing
close to 10atms and the prop slowed to a stop.
When I went to refill the air tank it regained it's pressure very quickly, in less
than 30 seconds. During past refills it took several minutes to refill the
tank from near empty to around 45atms.
It's almost like the system has reduced in volume somehow, any ideas where I might
start looking? In addition, the starter valve is sticking open; you take
your finger off the button and the starter stays open, not sure if it's a solenoid
issue or a button issue.
Thanks!
p.s. YMK has always been a hard starter; I know some of you only see 1-2 blades
before the engine kicks, we normally need over 10seconds before anything close
to sustained firing with lots of prime and skinned knuckles. Could this be
related?

Yeah, sometimes. Or maybe I just can't sleep and stuff like that ends

Well, delta-T * mass implies energy to me but you are right in that

Huh. And here I was going to call it Ethyne. I was forgetting that
was Acetylene.

OTOH, I suspect that MMO actually reduces the octane rating of the
fuel. We can certainly get away with it when burning 100LL in our low-
compression radial engines as we have huge detonation margins but
that might not be the case when running mogas.

Mozam,
Now you know why I say it is a reasonable replacement for the Viper!
Reasonable is all...for when retirement is final!
That is the standard fuel capacity with the acro tank and the Aux tank. TJ
has added a 8 inch section to his Aux tank increasing the capacity to ? 42
gal. Another mod has been to put two wet wing tanks in also. Which if I
remember correct add another 24 gal for a total of 58 gal. Or was it 60 gal
total
After flying the 52, at 52 power settings (65% and 650-700 mmHg) I am seeing
12 gph fuel consumption. That means I get about 2.5 hours vs 2 hours. My but
can't take anymore than that anyway.
A couple of guys added drop tanks out board of the gear also. I do not know
what their fuel capacity is with that mod.
Now you flew one...you are gonna want one!

Mr. Craig is your customer at that moment since I didnt hear any of you due
to the above reason. Even I know, whats wrong for me offering Mr. Craig? You
never even mentioned that you would like to be our sole authorized agent in US.
Thus, I assume weve done no wrong about offering other American clients.
Referring to the part list, you even used the word of steal. How can you say that?
Dont you know that? The part list is not your own private property even though
you put some to them on your web. It belongs to Hongdu, the manufacture of
CJ6. Therefore, we consider you have no right to claim that.
The last one, why did we not reply your mail in which you cursed everything? I
actually got one for you. But I sent it to my colleague asking her opinion since
she is the one who contacted with you before. However, she said she really
understood your feeling about knowing us trying to sell to your customer. Then,
I gave up that idea and hope you can calm down later.
But this time, I fell like I must give you a reply since you even behaved more
crudely. Dont you understand the American spirit of fair competition?
Business is business. After all, we still understand what youve done. We are the
supplier who enjoy close relations with many OEMs here. This is the key point.
Consequently, you declared were not welcoming in US market.
However, we firmly believe American people value the commercial spirit of fair
competition very much and it benefits all the customers.
Best regards,
frank

What MAP settings did you have when flying at 70%(you mention the throttle
adjacent to the prop lever).

Subject: Yak-List: Re: Mixture too rich?
I have a JPI FS-450 Fuel Flow in my -50 and it is accurate to about .2
Gallons at the end of a long flight, so I am confident the flow values are
correct.
At takeoff I get around 40 gph.
At 82% and full throttle around the 3000' to 6000' range it is not uncommon
to see anywhere from 25gph down low to 20+ up higher.
On a recent long cross country with low power cruise at maybe 70% and
throttle back (actually to about adjacent to the prop lever seems to work
well) we were consistently under 15gph, and more like 13 to 14.
I have my mixture trimmed pretty lean at idle, down to under 2.8 gph at 40%.
Like many M14s, mine will sometimes stumble when putting in throttle slowly
from idle. You can watch the fuel flow spike from idle flow under 3.0 to
about 13gph when it stumbles, then back to the stabilized flow once it
settles down.
The computer in the FS-450 is linked by a serial bus to the GPS and knows
where we are going and when we will be there. It also computes MPG and I
get about 11 Nautical miles per gallon. Mostly useless trivia I suppose.

Jorgen,
I do not know what the requirements are for your CAA. The FAA in the US
allows us to fly with the below lights on the wing tips. The lights that
Dennis has below with the link to Aircraft Spruce's website page for the
Whalen nav-position-strobe lights have the white aft facing position light.
They are mounted on both wingtips so you do not have to have a white light
on the tail. I have them on my 52. They work great.
As for the landing light, I have the light listed on page 444 of their
catalog. 90195 PAR 36 landing light (with lamp P/N 11-03286 -$283.95) That
is a 28V 4596 Lamp (GE Equivalent 250 W lamp). You will have to fabricate a
mounting bracket for the main gear. You can run the power one of two ways.
Run the wiring into the cockpit to a separate switch or tie into the gear
position indicator solenoid. Obviously you want the gear down side of the
circuit. I have been told that would work. Have not done it that way yet.
Just means that the gear lights come on every time you drop the gear.
I prefer to control the power to the gear light from the cockpit. I have
that the landing light I stated above but have mounted it on my plane yet.
To many other projects have gotten in the way.

Jorgen,
The best solution is the Whelen nav-position-strobe lights.
http://www.aircraftspruce.com/catalog/elpages/1105643.php
Although more expensive than the Aeroflash units, Aeroflash must have 2
power supplies for the strobe lights. The Whelen system uses one power
supply for both strobe lights.

Hi All
Looking for some ideas for lights to go on a Yak52.
So far I have cabin lighting off an L-39, and wingtip nav lights from L-29.
I need: white light for tail (how on earth would you fit something?)
Landing / taxi light. Thought to strap something to the gear.
Ideas? Suggestions?
Jorgen
