Dear Raimo,
As I remember I wrote sparkplugs, maybe to generic?
Maybe then only half right?
Most important is
What do we learn and how to avoid....(from your experience that is)
Thanks for sharing your experience!

Your friendly neighbor to the west, (Varberg Sweden)

Ps;
Will forward your discoveries to my friend Jan a local Europa owner.

You remember =93 one power selection and one rpm-selection only toget
her was acceptable to continue the flight with a reasonable vibra only.

s the engine was very unhappy. Why so =93 I am sure someone of you can
explain it. Certainly the plug has been very hot.

ots and gusting MUCH) grass strip. Soon until well over the ground at altitu
de +500 feet with full power and 2nd fuel pump still on and gears up I felt s
uddenly let us say medium or more shake and vibration. My immediate reaction
was to go around and land immediately but abandoned because wind was so fur
ious and I felt I cannot do that (a succesful landing).

it from fine to coarse, tried all the power settings and also a 2nd fuel fi
lter. Finally I noticed that when prop was in a climb mode (in my case 5400 r
pm /Rotax 912S) and MAP around 20 inches I got quite a comfortable flying mo
de and I headed straight home. My airspeed was w that selection about 110 kn
ots but because of a strong headwind GS was only about 70 knots (wanted to b
e clearly over the ground at 3000 ft because it was well over sunset and tot
ally dark, yesterday we got sunset around 1600 Zulutime and time was well ov
er 1630 when flying).

a bit worried my engine will separate or so. When trying to push more pwr i
t was more vibra and when trying to pull less pwr same. I Followed a main hi
ghway and decided to land there if feeling so. Cars there with lights are al
most like a lighted runway...
