Hi Raimo,
I am sorry to hear that your 912S is unhappy with 100LL. This is a bit
surprising for me as I have always used 100LL from Day 1 with no
problems. First flight was in Dec. 2001 and I now have 590 hours. Only
engine issue in that time has been a broken wire on an ignition system
connector which caused a problem on one magneto.
However, I have always used a fuel additive to prevent lead build up. I
first used TCP http://www.alcorinc.com/fuel-treatment/product-07-07.php
and now use Decalin http://www.decalinchemicals.com/fueladditive.html
additive. I see that TCP has problems with shipping now since the
solvent they use is toxic. TCP and Decalin have the same active
component, Tri Cresyl Phosphate, but Decalin has a benign solvent so it
can be carried in a plane. Decalin can be bought from Aircraft Spruce
http://www.aircraftspruce.com/catalog/appages/Decalin.php . I add 15 ml
of Decalin per 10 US gallons of fuel.
This routine seems to work well. I check the plugs at 50 hours and
change them at 100 hours as per Rotax recommendation; they are always in
good condition with no build up of lead. I also use Valvoline Durablend
10W-40 semi-synthetic oil (approved by Rotax). This oil picks up lead in
suspension and I get no deposit of lead sludge in the oil tank.
I also had problems with fuel coming from the breather vent during
filling. I fixed this by installing a larger diameter vent tube which
tees into the filler neck. The larger vent tube permits full flow
filling without backup. A small diameter tube goes from the filler neck
to the original fuselage top vent.
Hope the weather is warming up nicely for you.
Cheers, John

Subject: Europa-List: Refueling (Rotax)
All The Europa Refuelers,
I do not like to use 100LL (w Rotax).
That makes my engine (912S) unhappy, really.
So - if possible - I carry Mogas to the airfield.
That is not fun. I really hate it, to refuel it.
Same time, I do love to pump Cessna by 100LL.
More unfun is to refuel Europa by *normal* way because
- a canister is heavy to keep up
- it takes a long time to refuel even 60 litres = 3 cans
- it is unsafe for refueler=B4s health to be near when refueling
- there is a possibility [because of the contact between can and plane]
to flame and burn whole Europa and maybe your *whole life work*
- when almost full, it tends to come some fuel out from breathing tube
I think most of the problems are out w attached equipment. As you see
there is also for extra safety a real Europa fuel filter (they are extra
for me because I use one piece solid ones). In my case the fuel pump is
a cheap one - only 1,5 litres /minute - but so there is a good time to
check the plane! The power is taken from the `Jump Start` as in the pic
OR from my Europas EPS (External Power Source).
It took only 10 minutes to make this idea to live in Today.
