If you push a suitable rod (small screwdriver) up through the drain hole it will
retract the locking balls and push the pip-pin up without needing any special
tools.
This way you can make the pip pin holes just big enough for the pin itself.
We only worked this out after spending hours making a screw cap for the pip-pins
before deciding that a couple of cm of tape was neater, lighter and simpler.

Hi Dean
Check the oil pressure relief valve is not sticking, Or the spring isn't
damaged, At the same time i would change the oil and filter, I would use the
genuine Rotax oil filter, Another possibility is air is being drawn in to
the oil galley, Between the oil tank and pump, Also check the rubber sealing
ring on top of the oil tank.
http://www.ultralightnews.ca/rotax912/912-914oilPump.htm
Oil Filters
Only the Rotax-recommended oil filter (part 825 701) should be used. Only
those filters assure the correct pressure for bypass valve operation. Other
filters have less filtering surface and are not made to withstand the high
oil pressures the Rotax 4-stroke engines operate at.
To be avoided:
a.. Any other filter than Rotax part 825 701. There are no equivalents or
substitutes!
b.. Contrarily to what some rumours would like you to believe, Rotax does
not authorize the use of any other filter!

Peter,
The 914s have a mixture enrichment feature that kicks in at around 5000 rpm
to prevent detonation during boost. The TCU commands a 3-way solenoid to
switch from a low to high pressure source in the airbox effectively increasing
the pressure in the carb bowls via carb vents to slightly richen the mixture.
If the enrichment valve is not operating properly, you could be dumping too
much fuel in the mixture at the switching point. You may want to check this
valve.
Just a theory,
Tam

Subject: | Waste gate servo |
--> Europa-List message posted by: "Paul McAllister" <paul.mcallister@qia.net>
Hi All,
Yesterday when I powered up my aircraft I noticed the orange light flashing.
I power cycled again and I couldn't hear the servo moving. My frist
instinct was to suspect the waste gate sticking, but I think if the waste
gate is stuck then servo would move, but the cable would bow out. Any
thoughts ?
If I want to clean the waste gate shaft do I have to pull the muffler, or
will spraying the shaft with carburetor cleaner at the lever end do the
trick ?

Subject: | XS cowling ftting |
--> Europa-List message posted by: "Mike Gamble" <mp.gamble@tiscali.co.uk>
With engine orientated correctly (1.5* to stb) the top cowling overlaps the firewall
as expected but to the extent that the rearmost slot of the outlet vents
also half overlap the joggle.
I shall have to grind off the moulding and blank this vent off to fit the cowling.
Can I consider this par for the course or have I fallen into some trap that those
who have gone before can reveal?
Thanks chaps.

This is the first I have heard of such a significant overlap. To avoid a
potential major error take time to check your cowl fitting thoroughly.
The limitation of the fore-aft position of the cowl is determined by the
spinner backplate. I haven't got the manual with me at the moment so I
cannot refresh my memory as to the instructions provided. However I
remember Ian Rickard came up with a design for a small jig which was
temporarily fitted to the prop flange. This defined the position of the
cowl and provided a temporary support for it whilst the rear edges were
measured and trimmed. I described a technique for measuring and trimming
which was published in the Europa Flyer about 9 months ago along with
other firewall forward tips. You might find this useful if you look it
up.
As a quick cross check if you were to temporarily fit the spinner and
position the top cowl so it clears it by about 5mm you could then see
approximately the amount of overlap you need to trim.

Nigel Charles

The cowling is positioned reference the propeller. I made mine fit the 914S flange
and then found out the Airmaster required a little different fit.
I suggest you rethink the fit. It sounds to me you have missed something.

Mike:
My cowl is just like this probably 1/3 to 1/2 overlap. No problem, most
of my gill vents are blocked off on purpose. I don't want a bunch of air
blowing out over the top of the engine and out those gills. The air needs
to go down over the cylinders. So basically my last gill slot is ground
away where there is interference with the overlap, the air exits here and
the second to the last gill slot is open all the way. The rest have not
been opened up. You look into the last slot and mostly what you see is
the the overlap area. In my case I consider it a non issue.

Ron...I forward the following from Alex Bowman:
In answer to the query about the aft C of G parameters of the Europa
XS, when operating the craft at a gross over 1370 lbs: I fly C-GGHY
within the C of G range recommended in the Pilots Handbook and do so up
to a gross of 1500 lbs. but tend to stay approx. 1" away from the aft
limit. This tendency is not based on scientific calculations. In my
earlier life, as a military test pilot, I was aware that if you
increase the wing loading of a given model, the C of G range shrinks.
The dynamic & static longitudinal stability of the XS up to 1500 lbs.
gross, is very acceptable across the airspeed range flown.
.
Cheers, Alex
