Jeff, I had a somewhat similar problem once too. The wires to the ignition
module had broken internally. Fortunately I was able to repair them as a
new ignition module was, I think, priced at about $US 800.
Then last year I experienced an intermittent "surging" of the engine.
Couldn't get more than 4,000 RPM or the engine would start cutting out. I
checked all the usual suspects for problem areas and came up blank. I then
had the finest Rotax minds in the business pour over the engine with their
computers and engine analyzers, etc. They spent 4 weeks checking out the
entire engine, and swapping almost every accessory part, and guess what?
They could not determine the cause of the problem. They gave up.
Rotax is a pretty good engine......when it runs as it should. When it stops
running, God help you. It is so complex and there are so few people around
who are capable of diagnosing problems, if any at all, that you're flat out
stuck. I don't think I would buy another Rotax engine.

Not jumping on the band wagon but I'm having a similar problem. I discovered
sometime back this vibration that continued to get worse. After many
attempts at balancing the carbs and the sensenich carbon prop I finally
changed back to the warp drive 3 blade. I then had it balanced but It was
perfect. I balanced the carbs again and they we're almost perfect. Still at
2800 to 3000 static on the ground theres this annoying vibration. Maybe more
than annoying as I don't want to fly with it. Sitting at an idle static I
decided to do a 1800 to 2000 RPM mag check and noticed a smooth left / A mag
but a rough running right B mag. Spent days checking all the obvious stuff.
Plugs, wires with a timing light and still nothing. At this point I've had
two Rotax certified mechanics and we still have not solved the problem.
Trying to isolate the source we switched the 4 prong plugs going into the
mag's and the vibration was still on the B side. Finally we switched the 6
prong plugs going int!
o the coils and the vibration switched to the A or left mag on check.
Called Lockwood and they believe it's not in the coils but what else could
it be? Any thoughts would be appreciated. I'm not only frustrated but like
Remi I wish I had a thirsty Lycoming hanging on the front. Rotax may be
light and yes I know most swear by them but for me.... I just want to swear
at it.
Anyone working on trying the new UL power on the Europa.
