I think it depends on more than that.
The original twin conical airfilters lived under the cowling and picked up
hot air from inside the cowling, the later one piece air filter takes its
air from outside the cowling.
With the Classic firewall forward the cowling has the radiators at the front
and so the internal temperature is much greater than in the XS FWF
installation.
I agree that any misfiring might be a fuel quality problem, I assume you
haven't had any misfiring of any sort ?
I definitely was getting some minor hiccups after 40 minutes and on backing
off the throttle. I have now fitted the SkyDrive kit and will report back as
to whether the misfire is cured. (Proving a negative may take some while !)
I have no idea whether the 912S is any more likely to be prone to carb icing
than the 912 but the factors I mention above will certainly have and effect.

you made me think a little harder, so it wasn't wasted effort.
When you back off the lock nut the tension won't change, the nut just
behaves as a washer until the thread starts to bite in the opposite
direction, Ted put it slightly differently but said the same thing I think?

Carb icing has been found (and photographed) on 912. You may be lucky (or
wise) because of the characteristics of your installation but it certainly
can and does occur.

The 912S CAN suffer carb icing, and just becuase you have never experienced
it doesn't mean it doesn't exist. The classic cowling is less suceptable to
the problem I believe. I experienced it over Florida in the XS 912S trigear
company plane and its a little strange with a Rotax.

Hello,
I know this system, the big problem is the permanent upload charge of
electrical network during service 60w.
Personnaly I use Skydrive since 250 hours (I am very happy)and the two
main advantage are:
1 no electrical consumption
2 Permanent service (I had a valve into the cowling for shut down but I
never used)

Hi! Kingsley.
Well said, Mate ! But I don't think "beat on this subject" is an
offensive phrase. Just a statement about how much it dragged on which
was necessary to encourage the learning process about very deep and well
thought about problem by our engineering ancestors. I for one had chosen
to forget about it but when ever travelling by rail will take a lot more
interest. Thank the Lord for welded rails! Thanks Ted for the reminder
that our rail network may well be maintained by novices.(Sorry, the word
WELL isn't a word that should be used anywhere in Rail Engineering !)
Except I doubt they understand what a torque spanner is anyway.... just
use a 6ft bar on "fishplate" assemblies!!!!!!

Pops,
With respect mate, I don't think there was any beating going on with
respect to this subject.
Ted simply pointed out the correct way to use lock nuts, others
disagreed and still others like myself were mystified because we didn't
know. Never being afraid to admit I don't understand something, I asked
Ted for an explanation and now I'm pleased to be able to say I fully
understand the principles involved notwithstanding it took a little
while to grasp it.
I am of the belief this list and others are for the education of all and
I for one am grateful to Ted for what I have learned and I would not
like to see others put-off publishing or disputing list postings in

I believe you are wrong when you say there is a permanent 60w load on the
power bus. The ST system has 2x 15 watt heaters on each deicer module. They
can be switched independently and used together or separately.
The total load on all 4 heaters (2 per carb) is 60 watts but in flight it
would be sufficient to only utilise half the load to keep the carbs warm.
The additional 30 watts could be switched in on takeoff and landing (or when
needed).
Unless you are running an incredibly complex panel you shouldnt be needing
the output which the alternator is capable of delivering.
The only reason I am considering these is because I am retrofitting my
heating system and I dont wish to have to drain down the radiators etc.
If I had the choice (ie: prior to completing our Europa) I would have
definitely opted for the skydrive system as I think it is an inherently
better design ( it can be left on permanently and consumes negligible power/
energy). My main issues are with the installation process.
My only concern over the ST system is that the heatsource is somewhat
localised (heater is bolted to the LHS of the carb whereas the Skydrive
system distributes the heat evenly where it is required.
From what I have been told the Skydrive is difficult to fit and really
requires a hydraulic press to force the heater unit inside the carb body. I
wonder how many have been split/ damaged in the process.
Does anybody know if Skydrive offer a fitting service. I would be concerned
that I might be picking up the cost for a new carb unit if anything went
wrong.

With no mechanical aptitude and with much trepidation I fitted a Skydrive.
The hardest part was finding a wide enough vise to press the fitting on.
After taking care to ensure that it was fitted squarely, the assembly went
well, however I could see that it is the kind of job that could easily
spoil your day.

After buying the skydrive system, I take 2 hours to install on my 912
without any problem on the carburettor.
My main problem is to modify the fuel cup below the carburettor. I have
made a new cup design and modify the original cup by welding an addition
lenght of 19 mm.
See the drawings joint.

Hi! Peter.
Re:- "Scandinavian Sortie" Europa Flyer.
Not wishing to be pedantic but G-PTAG must have credit where it's due !
G-PTAG Europa KIT 337/MKI/Jabiru 3300 with myself and Ivor Phillips was
the FIRST EUROPA TO FLY IN FINLAND 3 YEARS AGO, but also kind courtesy
of Raimo Toivio and his beautiful family and state of the art
accommodation and sauna . Now if you were to say the first Mono Rigged
Europa or Rotax powered Europa I'd retire gracefully on the matter !
Who has lined up this years trips yet? Where and when. I'm looking to
possibly do Barkaby and Stauning which are consecutive weekends with
possibly Estonia, Latvia and/or Poland in the interceding week or
en-route out ward or return. I also probably need a prop. overall at MT
Propellers in Bavaria late summer and a trip to Portugal as a forerunner
to a WINTER HOLIDAY in the very south which I'd like to take the 'plane
on. Not to forget the Swiss Rally too! And I believe also that it's a
Friedrichshafen Year too.?

The 912S with XS cold air plenum can DEFINITELY get carb ice, don't
doubt it for a moment, both on the ground and in the air. The Skydrive
carb heat clears the ice quickly once turned on. We only turn it off
when we expect to do a hot start after a flight, letting the carbs cool
on the taxi to the ramp after landing.

I came to the same conclusion as the carbs were definitely not round enough
to even hold the heater on a thou or two while being put into the vice. In
the end, rather than risk a 400 or more carb (or two !) I sent them back to
SkyDrive and they fitted them for 15. OK the postage added another 30 but
I considered it money well spent !
In fact my recommendation is that you take your carbs off and send them to
SkyDrive and order the heaters and their fitting at the same time. That way
you don't pay for an extra leg of the journey for the heaters. I am sure it
only took them 15 minutes and I am sure you could go there and have it done.
If I had realised how expensive the postage was (18 from me to them) I
would have driven up there !
Like many things someone who has done 50 such pressings will be more aware
of the limitations and the level of force required. I didn't, so it was
worth the extra 50.
Draining the water system is trivial. Take off Air filter (you would have to
do that anyway to get the carbs off). Take off water filler cap. Put bowl
underneath bungey. Be ready to move bowl. Use Stanley knife to cut the pipe
at the back of the engine just below the flywheel cover (and THAT is an over
description of a flimsy bit of plastic that does not keep water out of the
flywheel housing !). Make a decisive cut. Water p*sses out, into bowl which
you move to catch as much as possible to avoid having to clean it up off the
floor. (You won't be re-using it !)
After inserting the t-pieces and replacement of the heater connected carbs,
fill up the water and bleed the pipe between the heaters as specified in the
instructions. And Bob is your mother's brother !

Subject: | Manifold pressure gauge |
--> Europa-List message posted by: Richard Holder <rholder@avnet.co.uk>
Hi, just received the Dec 2004 issue of the Europa Flyer.
I am very interested to see that Brian Allsop managed to get his Kremen
CS/VP prop approved without a manifold pressure gauge.
When I put my Airmaster on my aircraft at the initial build I saw that
Airmaster and Rotax did not require a MAP and so built my panel accordingly.
When it came to the Permit to Test Fly Donaldson INSISTED on the fitting of
a MAP. I argued that there was no requirement from the manufacturer of
either bit of kit. He insisted. Sending me a copy of some JAR "minimum
equipment" list which showed that a MAP was required for a CS prop. Probably
written in 1948 !
Anyway he is the king of this stuff and I had no option but to fit it
(spitting !) on a sub-panel that destroyed the looks of my panel.
Actually it is very useful for setting power.
So how come Brian didn't need one ? It is only required for CS props - not
VP props.
I am interested about the description of VP and CS in the article. The
Airmaster gives a VP option just as an aside. I have not used it yet. The
Airmaster controller has switched positions for Take-Off (5700 rpm) Climb
(5400) and Cruise (5000) plus a position where you can set any rpm you want.
The Kremen seems to be a mixture of CS and VP almost as separate functions,
when really the CS could be used all the time if all the required features
are there.
Unless someone disagrees !
:-)

I totally agree with the bit about paying Skydrive to fit the carb heater modules.
Draining the water system is trivial. Take off Air filter (you would have to
do that anyway to get the carbs off). Take off water filler cap. Put bowl
underneath bungey. Be ready to move bowl.
OK so far
Use Stanley knife to cut the pipe
at the back of the engine just below the flywheel cover (and THAT is an over
description of a flimsy bit of plastic that does not keep water out of the
flywheel housing !). Make a decisive cut. Water p*sses out, into bowl which
you move to catch as much as possible to avoid having to clean it up off the
floor. (You won't be re-using it !)
Unless I have read this wrong heres another reason I dont want to attempt this.
On the original Classic engine assembly, there is virtually no space between
the firewall and the back of the engine (my engine dosent have the plastic cover
that you mention). It would be damn near impossible to make the cuts that you
describe without removing the engine and unless the engine breaks I dont intend
to take it off.
If I have got this wrong, let me know.

As per the instructions, I taped the heater housing on the carbs with
heavy mason hammer insulated with a piece of pine wood. Went very slow
to be sure they we're level and on straight. When I couldn't find a
vice that was wide enough to push them together I just continued to use
the hammer a little at a time and they went together perfect. I'm sure
Sky Drive doesn't recommend this but it worked well. We are approaching
starting this thing up so well let you know if it didn't.

Like so many others I didn't fit a tap. Thought leaving it on couldn't
hurt anything. Does it need to be off for a hot start?

Hi Carl,
Mine's a 912 Classic, but I didn't remove the engine. I removed the pipe,
cut it, inserted the tee and pipe and then put it back. Fiddley, but
doable. My heaters have done about 600 hrs without any problems and give
much confidence.
Good luck,
William

In very hot weather the carb will be left hot at the end of a flight. If you
are planning to start again in (say) the next 30 minutes - when the engine
is still hot - then you need to turn off the tap after landing on the first
flight to give the carb heaters a chance to cool down before shut down. Open
the tap again before take-off.
The SkyDrive instructions say that the tap is not needed in our UK temperate
climate, but in very hot environments then turning it off keeps the carbs
cooler (if necessary !) (eg the desert in the US)

Thanks for your input William, sounds encouraging.
Just looking at my engine manuals, I dont understand why the return pipe has
to be attached so close to the water pump inlet. It would seem that anywhere
in the return line would have the same result. Cutting the pipe where it
runs along the top of the engine would be much easier and would be far less
messy.
Anyone know of a good reason why this wont work.
Presumably the other end of the circuit is connected somewhere between the
expansion tank and the radiator inlet connection. Or is it between the top
return manifold and the expansion tank (probably higher water pressure at
this point).
Does anyone have a copy of the installation instructions that I could have.

The top takeoff point is between the top collector where the pressure cap
sits, and the #2 cylinder head (left front cylinder).
A t piece goes in there and a pipe goes to the left hand heater. Then from
the left hand heater to the right hand heater, and then from the right hand
heater to a t-piece put into the pipe from the bottom of the engine that
goes to the radiator.
I think you need a "head" of water in the heating circuit otherwise you may
end up with an airlock.
NOT in the expansion pipe between the top collector and the overflow bottle.
That would be crazy !
Best to RTFM ! (read the flipping manual !) AND follow them !

We have had problems with hot starts on hotter days, you could smell the
gas getting boiled out of the carbs. Starting was difficult until the
engine cooled down (we learned to watch the carb heat gauge). Turning
off the carb heat immediately after exiting the runway helped a lot with
the hot starting. By the time we got back to the hanger, the carb heat
would be down to nearly ambient, vs well above 50 degC if the carb heat
is left on (the carb heat gauge does not register about 50 degC). We
normally run auto gas, which may make the problem worse because of its
lower vapor pressure/boiling temp compared to 100LL.

Carl, I think you'll find that the heater elements are two at 30w in each
heater, So total load upto 120w.
Another thing to consider is that these seem to be proven on the Jabiru
(with its carb buried at the back of the engine not far behind the exhaust),
but you'll be entering the experimental arena by fitting them to the 912.

I seem to have hot start problems at carb temps. above about 35C; what
'threshold' have you experienced (other than somewhere above 50C)?

Subject: | Manifold pressure gauge |
--> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk>
Hi! Richard
I find myself a little bemused why the resistance to fitting a Manifold
Pressure Gauge, apart from needing room on the panel? If you have a CS
installation without the gauge you will have no indication as to how you
are loading the engine, that is to say RPM is no longer an indication of
power.
So it becomes possible to run the engine at all RPM in a labouring
condition not to be recommended for cruise configuration with respect to
fuel consumption and engine well being. My MT CS prop. will hold the
engine RPM at say 2,500 even with maximum MP at say 30 inches, where
maximum recommended is about 22 inches. The rule of thumb is so called
"squared"
Which means 24" FOR 2,400 rpm ON A DIRECT DRIVE ENGINE. However I've
managed to identify on the Jabiru 3300 that a lower MP with a slightly
higher RPM gives a better fuel performance. (no snipes about fuel usage
comparison with the Rotax thanks Duncan the scenario still applies)
Problem without a MP Gauge is knowing the effect of the ambient and
altitude changes and in pressure relative to engine performance.

--> Europa-List message posted by: Richard Holder <rholder@avnet.co.uk>
Hi, just received the Dec 2004 issue of the Europa Flyer.
I am very interested to see that Brian Allsop managed to get his Kremen
CS/VP prop approved without a manifold pressure gauge.
When I put my Airmaster on my aircraft at the initial build I saw that
Airmaster and Rotax did not require a MAP and so built my panel
accordingly.
When it came to the Permit to Test Fly Donaldson INSISTED on the fitting
of
a MAP. I argued that there was no requirement from the manufacturer of
either bit of kit. He insisted. Sending me a copy of some JAR "minimum
equipment" list which showed that a MAP was required for a CS prop.
Probably
written in 1948 !
Anyway he is the king of this stuff and I had no option but to fit it
(spitting !) on a sub-panel that destroyed the looks of my panel.
Actually it is very useful for setting power.
So how come Brian didn't need one ? It is only required for CS props -
not
VP props.
I am interested about the description of VP and CS in the article. The
Airmaster gives a VP option just as an aside. I have not used it yet.
The
Airmaster controller has switched positions for Take-Off (5700 rpm)
Climb
(5400) and Cruise (5000) plus a position where you can set any rpm you
want.
The Kremen seems to be a mixture of CS and VP almost as separate
functions,
when really the CS could be used all the time if all the required
features
are there.
Unless someone disagrees !
:-)
Richard

Hi Duncan,
I'm sorry, but I haven't really paid that much attention to the specific
temperature that could be used as a go/no-go threshold. I do know we
still had problems starting when the temp was just below 50 degC (the
max readable on our carb temp gauge). If I had to guess, I would say 35
degC might be a reasonable threshold.
I do know that what we have had carb ice, the carb temp has been in the
vicinity of +2 degC.
regards,
Terry

I dont have the manual, thats why i'm guessing !
Didnt mean the overflow pipe but the section between the return manifold
(where all the outputs from cyl heads come together) and the expansion tank
(where the pressure cap is fitted). On mine it is a section of pipe about 4
inches long, but I believe mine is a one off. Our engine is the original
engine fitted to G-YURO (must be about 12 years old).
There is almost certainly be a pressure differential between these two
points because they are short circuiting the radiators. It might be
necessary to clamp the upstream radiator hose initially to purge any air
from the carb heater system.
No doubt i'm reinventing the wheel.
As you say, read the instructions. (but I dont have a copy?)

Hi Bob,
I would not say that MAP is the only way to measure power when equipped
with a constant speed prop. We find that fuel flow is also a good
indication of relative power, using it probably more often than MAP.
Although with the 912 and 912s, the mixture gets richer at altitude,
making the fuel flow reading somewhat higher than at sea level, for the
same power (MAP, HP, etc.).
regards,
Terry Seaver

Carl,
You worry too much. Just follow the instructions from Skydrive. There is no
need to drain the system, just a topup to replace spilled coolant. I used a
large vise for pushing on the heater bodies, a job which took about 10
minutes. Be sure everything is square, then just turn the handle and keep it
moving slowly and steadily.
So far I had no problems with hot starting, but then I usually open the
inspection doors on top of the cowling if it is just a refuelling stop.

Subject: | Manifold pressure gauge |
--> Europa-List message posted by: "R.C.Harrison" <ptag.dev@tiscali.co.uk>
Hi! Terry
I didn't actually say that the MP Gauge was the ONLY way to read the
power.
I do consider that it is the most versatile being able to read just what
is entering the engine.
However I would guess that you could still be "labouring" the engine to
just rely on fuel flow without some very extensive charts covering power
output at differing ambient temps. pressures and humidity all relative
to altitude.

Hi Bob,
I would not say that MAP is the only way to measure power when equipped
with a constant speed prop. We find that fuel flow is also a good
indication of relative power, using it probably more often than MAP.
Although with the 912 and 912s, the mixture gets richer at altitude,
making the fuel flow reading somewhat higher than at sea level, for the
same power (MAP, HP, etc.).
regards,
Terry Seaver

Redman Nichols have apparently learnt their trade from the many examples of
fraud they have had presented to them in the past.
I have been told that even though Sharon held back cheques for orders she
knew could not be delivered, the Administrator paid them into EMIL's
account, AFTER the company was in admistration. In the full knowledge that
nothing would be delivered.
That sounds like fraud to me. I wonder how much of a cut Kwislon paid him.

Pops!
you made me think a little harder, so it wasn't wasted effort. When you back
off the lock nut the tension won't change, the nut just
behaves as a washer until the thread starts to bite in the opposite
direction, Ted put it slightly differently but said the same thing I think?

Hi
I do agree (and said so) that the MAP does allow that measure. However there
is NO requirement by Rotax or Airmaster for any restriction in the
combination of rpm and MAP. None whatsoever, certainly no requirement for
square.
I was spitting because I had finished the panel and everything was ready.
And Airmaster AND Rotax said that there was no requirement for the gauge.
I had to add the MAP to a sub-panel which destroyed the symmetry and lines
of the panel. I certainly wasn't going to re-design at that stage. [I am in
the process of re-designing now, with the MAP gauge in-panel, but it may not
see the light of day for some time as flying is more important than the
engineering now that it is running !]
My running norm is 5000/25.5 inches
I tried 4600/26 which gave the same speed but over 200 litres made no
difference to the fuel consumption. If anything it went up ! (that is
consistent with your information) but I don't want to run faster than 5000
so I am sticking with 5000/25.5 which gives around 120 knots at 16.2 litres
per hour. Oops I wasn't supposed to say that ! :-)

The coolant can be 'drained' without coolant all over the engine or the

the hose going to the radiator and put the syphon tube in it, pushed down to
the bottom, and syphon out the rest.
